This book was released on 2008 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gallium arsenide shows excellent promise for terahertz generation using mid infrared. This is for two reasons. First, the indices of refraction for the terahertz (n[subscript THz]=3.61 at 1 [subscript THz]) and mid infrared (n[subscript opt]=3.431 at 2 [mu]m) are close allowing a long interaction length. Second, the linear absorption is low at terahertz frequencies [alpha][subscript THz]=.5 to 4.5 cm−1 for 1 to 3 [subscript THz]). Since gallium arsenide is a direct bandgap material, multiphoton absorption and nonlinear refraction are issues for efficiency and system design in the mid infrared. In fact, linear absorption makes this material opaque at or below 870 nm. Additionally, two photon absorption is quite pronounced between 870 nm and 1.74 [mu]m. I will present the theory then the experimental data for two and three photon absorption (870 nm to 1.74 [mu]m and 1.74 [mu]m to 2.61 [mu]m, respectively) as well as for nonlinear refraction. The three photon absorption has a minimum at 2 [mu]m in the spectral range of 1.74 to 2.61 [mu]m thus it is the preferred wavelength for terahertz generation. At 2 [mu]m the anisotropy in the three photon absorption was almost 50 %. The nonlinear refraction remains fairly constant in this range as expected. However at 2 [mu]m the anisotropy in nonlinear refraction was only 16% as compared with the predicted factor of 2. Qualitatively, the anisotropic behavior of the nonlinear refraction still conforms to the expected symmetry class of zincblende crystals. Terahertz time domain spectroscopy will be discussed on both theoretical and experimental levels. The results will show that terahertz generation is promising in the mid infrared range for wavelengths 2 [mu]m and above. At 2 [mu]m I demonstrate the advantages of a quasi-phase matched structure. One, the inverting structure generates a narrow band source. Additionally, shaped domains map to the terahertz electric field allowing shaped pulses. Also, of benefit is the increase in power production from having a longer effective interaction path in the crystal.

Download or read book Properties of Aluminium Gallium Arsenide written by Sadao Adachi and published by IET. This book was released on 1993 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alloy system A1GaAs/GaAs is potentially of great importance for many high-speed electronics and optoelectronic devices, because the lattice parameter difference GaAs and A1GaAs is very small, which promises an insignificant concentration of undesirable interface states. Thanks to this prominent feature, a number of interesting properties and phenomena, such as high-mobility low-dimensional carrier gases, resonant tunnelling and fractional quantum Hall effect, have been found in the A1GaAs/GaAs heterostructure system. New devices, such as modulation-doped FETs, heterojunction bipolar transistors, resonant tunnelling transistors, quantum-well lasers, and other photonic and quantum-effect devices, have also been developed recently using this material system. These areas are recognized as not being the most interesting and active fields in semiconductor physics and device engineering.

Download or read book Nonlinear Photonics Devices written by Luigi Sirleto and published by MDPI. This book was released on 2021-01-11 with total page 212 pages. Available in PDF, EPUB and Kindle. 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.
