Book excerpt: Le silicium est le fondement de la microélectronique, pour laquelle des milliards de dollars et des décennies de recherche ont été consacrés au développement de l'industrie de la fabrication. Après avoir surmonté un certain nombre d'obstacles techniques difficiles, cette technologie a atteint une maturité, une rentabilité et un processus robuste. La photonique à base de silicium a récemment fait l'objet d'une grande attention en raison de la demande mondiale croissante de données issues des télécommunications. Le silicium, matériau transparent dans les spectres du proche et du moyen infrarouge, permet de concevoir des circuits optiques basés sur cette plate-forme. Tirant parti de l'infrastructure et de l'expertise de la fabrication microélectronique moderne, la photonique de silicium offre de nombreux avantages attrayants en réduisant la taille, la consommation d'énergie et le coût de fabrication, ainsi qu'un grand potentiel de production de masse. Les progrès récents de la photonique de silicium ont permis aux concepteurs d'avoir accès à des librairies de blocs de construction passifs et actifs tels que des multiplexeurs, des résonateurs en anneau, des modulateurs, des photodétecteurs, etc. Ces avancées ont incité les chercheurs à exploiter cette plateforme dans divers domaines allant de la détection à la médecine. L'un des défis de la recherche sur la photonique du silicium est de développer une source de lumière et un amplificateur compatible avec le silicium en raison des bandes interdites indirectes du silicium et du germanium. Plusieurs solutions sont actuellement à l'étude pour fournir des sources de lumière sur puce, qui sont réalisées comme suit : lasers à commande électrique par manipulation de la bande interdite et méthodes de co-intégration ou lasers à commande optique par co-intégration de matériaux de gain, dopage d'un matériau de revêtement avec des ions de terres rares, ou utilisation d'effets non linéaires pour convertir la fréquence. La manipulation de la bande interdite implique l'ingénierie de la bande interdite des matériaux du groupe IV avec des souches ou des alliages pour améliorer l'émission directe de la bande interdite. Les techniques de co-intégration comprennent la croissance épitaxiale hétérogène ou le collage de matériaux du groupe III-V sur le guide d'ondes en silicium pour concevoir un laser ou tirer parti de caractéristiques à gain élevé. Le dopage d'une gaine de verre avec des éléments de terres rares comme le thulium, l'holmium, l'erbium avec des guides d'ondes spécialement conçus pour former une cavité laser a également été proposé comme solution. La conversion de fréquence par des effets non linéaires dans les guides d'ondes en silicium est une autre approche de la génération de lumière sur puce qui peut être réalisée sans aucun post-traitement des puces en silicium sur isolant (SOI). Par exemple, dans le silicium, la non-linéarité du troisième ordre permet la génération de peignes, la génération de supercontinuum, l'oscillation paramétrique optique et l'émission Raman. Parmi celles-ci, la diffusion Raman-Stokes stimulée (SRSS) peut être avantageusement utilisée pour la conversion et l'amplification des longueurs d'onde, car elle ne nécessite pas d'ingénierie de dispersion. Le gain Raman du silicium a donc été exploité dans la conception de divers lasers et amplificateurs sur puce. Les lasers et amplificateurs Raman sur puce utilisent des conceptions simples et ont jusqu'à présent été réalisés principalement avec des tranches de silicium relativement épaisses. Dans ce travail, nous profitons du gain Raman pour étudier, modéliser, concevoir et démontrer expérimentalement un laser et un amplificateur Raman. Nos recherches s'appuient sur une fonderie à accès libre offrant des plaquettes SOI standard avec une épaisseur de silicium de 220 nm. Dans notre première contribution, nous présentons un modèle complet pour un laser Raman CW dans une plateforme SOI. Nous concevons ensuite un laser Raman de 2,232 μm avec une cavité résonante en anneau sur puce. Les valeurs optimisées pour la longueur de la cavité et les rapports de couplage de puissance sont déterminés par la simulation numérique des performances du laser en tenant compte des variations de fabrication. Enfin, en concevant un coupleur directionnel (DC) accordable pour la cavité laser, une conception robuste du laser Raman est présentée. Nous montrons que la réduction des pertes de propagation et l'élimination des porteurs libres, par l'utilisation d'une jonction p-i-n, amélioreront de manière significative les performances du laser Raman en termes de réduction de la puissance de seuil et d'augmentation de l'efficacité de la pente. Dans notre deuxième contribution, nous démontrons un laser Raman accordable de haute performance qui convertit la gamme de longueur d'onde de pompe de 1530 nm - 1600 nm à la gamme de signal de 1662 nm- 1745 nm avec une puissance de sortie moyenne de 3 mW à ~50 mW de puissance de pompe avec un seul dispositif. La caractéristique principale de ce laser est l'utilisation d'un mécanisme de couplage accordable pour ajuster les coefficients de couplage de la pompe et du signal dans la cavité en anneau et compenser les erreurs de fabrication. Nos résultats sont très prometteurs pour l'augmentation substantielle des ressources spectrales optiques disponibles sur une puce de silicium. Nous démontrons également, pour la première fois, un laser Raman dans l'infrarouge moyen générant un signal à 2,231 μm avec une pompe à 2 μm et étudions les défis d'obtenir une émission cette bande. Notre dernière contribution est dédiée à l'amplificateur Raman, nous discutons et validons expérimentalement l'importance de considérer le gain Raman non-réciproque en utilisant une pompe et une sonde contre-propagatives ou co-propagatives, différentes longueurs d'amplificateur, puissances de pompe d'entrée et valeurs de perte non-linéaire. Nous démontrons un circuit optique sans perte assisté par Raman dans un guide d'ondes de 1,2 cm de longueur qui atteint un gain net nul avec seulement 60 mW de pompage en puissance continue. Nous examinons les pertes non linéaires des guides d'ondes en silicium pour estimer la durée de vie des porteurs libres (FCL), puis nous extrayons le coefficient de gain Raman du guide d'ondes photonique en silicium. Nous utilisons ensuite ces paramètres clés comme entrée d'un modèle d'amplificateur Raman photonique au silicium pour trouver la performance optimale en fonction de l'encombrement et de la puissance de pompage disponibles.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of Raman gain in optical fibers and its applications in communication systems have been well recognized since early 1970's. Due to broad stimulated gain bandwidths, Raman amplifiers and tunable lasers have become excellent devices for long haul and broadband optical communication networks. In this thesis we demonstrate the construction of cost effective and efficient ring Raman lasers. The ring lasers are constructed using wavelength division multiplexing (WDM) couplers and a variety of germano-silicate (GeO[subscript]2/SiO[subscript]2) fibers namely Corning SMF-28, HI-1060, and HI-980. We also demonstrate a compound ring Raman laser in SMF-28 fiber with double WDM couplers connected in parallel that generates up to 6th order cascaded Stokes, operating near 1572nm, using a Yb-doped fiber laser pump at 1117nm. The output power of this laser is 0.65W for an input power of 4.2W and hence a conversion efficiency of 15%. Another compound ring Raman laser in HI-1060 with double WDM couplers in series configuration has been demonstrated which generates up to 4th order Stokes near 1350nm, with the same input power. The comparison of the experimental results obtained from both single-coupler and double-coupler ring Raman lasers along with a possible explanation for the results using relevant theory have been presented. A Raman fiber amplifier has also been demonstrated in which gain is provided by transmission fiber itself. Using a pump of 700mW power at 1480nm wavelength, a gain of l6dB has been obtained near 1584nm. In order to obtain uniform gain over a broad band, a distributed Raman amplification (DRA) technique has been used. The gain flattening over a wideband is achieved using multi-[lambda] pumping. Simulation results show that about I0dB gain can be achieved in a %7E50nm band at wavelengths ranging from 1560-1610nm using 6-[lambda] pump in 1460-1510nm range.

Available in PDF, EPUB and Kindle. Book excerpt: Micro- and nanophotonics explore behavior of light on the micro-/nanoscale and the interaction of micro-/nanoobjects with light. The driving force for their development is the aim to go beyond the limit of photonics. Because of the diffraction limit, photonics components are not able to confine light to the microscale or nanoscale dimension; therefore, one of the key challenges for micro- and nanophotonics is a reduction in the size of integrated optical devices, while maintaining a high level of performance. As far as light amplifiers and laser sources based on stimulated Raman scattering (SRS) are concerned, important accomplishments have been achieved in the fields of fiber optics amplification and integrated photonics devices. In this chapter, the most interesting investigations in the field of stimulated Raman scattering in micro- and nanophotonics are reviewed. These findings provide promising perspectives for integrated micro-/nano-Raman lasers.

Book excerpt: The first nonlinear optical effect was observed in the 19th century by John Kerr. Nonlinear optics, however, started to grow up only after the invention of the laser, when intense light sources became easily available. The seminal studies by Peter Franken and Nicolaas Bloembergen, in the 1960s, paved the way for the development of today’s nonlinear photonics, the field of research that encompasses all the studies, designs, and implementations of nonlinear optical devices that can be used for the generation, communication, and processing of information. This field has attracted significant attention, partly due to the great potential of exploiting the optical nonlinearities of new or advanced materials to induce new phenomena and achieve new functions. According to Clarivate Web of Science, almost 200,000 papers were published that refer to the topic “nonlinear optic*”. Over 36,000 papers were published in the last four years (2015–2018) with the same keyword, and over 17,000 used the keyword “nonlinear photonic*”. The present Special Issue of Micromachines aims at reviewing the current state of the art and presenting perspectives of further development. Fundamental and applicative aspects are considered, with special attention paid to hot topics that may lead to technological and scientific breakthroughs.
