Book excerpt: Optical interconnects is a promising technique to boost the speed of electronic systems through replacing high speed electrical data buses using optical ones. Optical coherence tomography is an attractive imaging technique that has been widely used in medical imaging applications with capability of high resolution subsurface cross sectional imaging in living tissues. Both the optical interconnects and the optical coherence tomography imaging may benefit from the use of integrated optics technology in particular polymer waveguides that can be designed and fabricated to improve the device capability, system compactness, and performance reliability. In this dissertation, we first present our innovative design and realization on the polymer waveguides with 45° integrated mirrors for optical interconnects using the vacuum assisted microfluidic (VAM) soft lithography. VAM is a new microfluidic based replication technique which can be utilized to improve the performance of imprinted devices by eliminating the residue planar layer and accomplish complex devices incorporating different materials in the same layer. A prism-assisted inclined UV lithography technique is introduced to increase the slanted angles of the side walls of the microstructures and to fabricate multidirectional slanted microstructures. It is also used to fabricate 45° integrated mirrors in polymer waveguides to support surface normal optical coupling for optical interconnects. A dynamic card-to-backplane optical interconnects system has also been demonstrated based on polymer waveguides with tunable optofluidic couplers. The operation of the tunable optofluidic coupler is accomplished by controlling the position of air bubbles and index matching liquid in the perpendicular microfluidic channel for refractive index modulation. The dynamic activation and deactivation of the backplane optofluidic couplers can save the optical signal power. 10 Gbps eye diagrams of the dynamic optical interconnect link have been demonstrated showing the needed high performance optical interconnection. The design and fabrication of planar concave grating (PCG) wavelength demultiplexer on SU-8 polymer waveguides is presented for wavelength division multiplexing system to further support optical interconnection applications. The PCG wavelength demultiplexers with a flattened spectral response are accomplished by innovative design of a multi-mode interference coupler as input to the PCG. The mode field distribution at the PCG planar input is controlled by adjusting the width of an input waveguide taper connected to multi-mode interference coupler. By extending the channel number and density, the PCG wavelength demultiplexer can become a compact optical spectrometer which could be used to realize a portable optical coherence tomography system. The design of a 200-channel and a 1024-channel PCG spectrometers with low crosstalk, small channel loss, good uniformity, and chip size of 3 cm x 3 cm and 8 cm x 8 cm, respectively, has been performed. An alternative quicker solution using cylindrical optics with a vertical beam size of about 3 mm in the diffraction plane is also demonstrated to achieve a compact optical spectrometer, which is capable of supporting optical coherence tomography subsurface imaging applications.
Book Synopsis Optical Polymer Waveguides by : Jörg Franke
Download or read book Optical Polymer Waveguides written by Jörg Franke and published by Springer Nature. This book was released on 2022-12-06 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light signals in optical waveguides can be used to transmit very large amounts of data quickly and largely without interference. In the industrial and infrastructural sectors, e.g. in the automotive and aerospace industries, the demand to further exploit this potential is therefore increasing. Which technologies can be used to effectively integrate systems that transmit data by means of light into existing components? This is a central question for current research. So far, there have been some technical limitations in this regard. For example, it is difficult to couple the signal of an optical waveguide to other optical waveguides without interruption. There is also a lack of suitable fabrication technologies for three-dimensional waveguides, as well as design and simulation environments for 3D opto-MID. This book addresses these and other challenges.

This book was released on 2013-10-17 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to integrated optical waveguides for information technology and data communications. Integrated coverage ranges from advanced materials, fabrication, and characterization techniques to guidelines for design and simulation. A concluding chapter offers perspectives on likely future trends and challenges. The dramatic scaling down of feature sizes has driven exponential improvements in semiconductor productivity and performance in the past several decades. However, with the potential of gigascale integration, size reduction is approaching a physical limitation due to the negative impact on resistance and inductance of metal interconnects with current copper-trace based technology. Integrated optics provides a potentially lower-cost, higher performance alternative to electronics in optical communication systems. Optical interconnects, in which light can be generated, guided, modulated, amplified, and detected, can provide greater bandwidth, lower power consumption, decreased interconnect delays, resistance to electromagnetic interference, and reduced crosstalk when integrated into standard electronic circuits. Integrated waveguide optics represents a truly multidisciplinary field of science and engineering, with continued growth requiring new developments in modeling, further advances in materials science, and innovations in integration platforms. In addition, the processing and fabrication of these new devices must be optimized in conjunction with the development of accurate and precise characterization and testing methods. Students and professionals in materials science and engineering will find Advanced Materials for Integrated Optical Waveguides to be an invaluable reference for meeting these research and development goals.

This book was released on 2015-12-21 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic of the BPM technique in the frequency domain relies on treating the slowly varying envelope of the monochromatic electromagnetic field under paraxial propagation, thus allowing efficient numerical computation in terms of speed and allocated memory. In addition, the BPM based on finite differences is an easy way to implement robust and efficient computer codes. This book presents several approaches for treating the light: wide-angle, scalar approach, semivectorial treatment, and full vectorial treatment of the electromagnetic fields. Also, special topics in BPM cover the simulation of light propagation in anisotropic media, non-linear materials, electro-optic materials, and media with gain/losses, and describe how BPM can deal with strong index discontinuities or waveguide gratings, by introducing the bidirectional-BPM. BPM in the time domain is also described, and the book includes the powerful technique of finite difference time domain method, which fills the gap when the standard BPM is no longer applicable. Once the description of these numerical techniques have been detailed, the last chapter includes examples of passive, active and functional integrated photonic devices, such as waveguide reflectors, demultiplexers, polarization converters, electro-optic modulators, lasers or frequency converters. The book will help readers to understand several BPM approaches, to build their own codes, or to properly use the existing commercial software based on these numerical techniques.

Book Synopsis Fabrication of Optical-mode Converters for Efficient Fiber-to-silicon-waveguide Couplers by : Raúl E. Barreto
Download or read book Fabrication of Optical-mode Converters for Efficient Fiber-to-silicon-waveguide Couplers written by Raúl E. Barreto and published by . This book was released on 2006 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical-mode converters are needed to efficiently couple light from an optical fiber to a photonic circuit by matching and transforming the propagating modes. This work is based on a horizontally-tapered coupler, in which light from an optical fiber is coupled into a large polymer waveguide and then gradually transferred to a smaller silicon waveguide whose width increases with distance along the guide. Several devices were designed and fabricated to measure the efficiency of the coupler. E-beam exposure doses and writing strategies were optimized to create the tapered silicon waveguides. A fabrication process was developed to form the polymer waveguides without etching the underlying silicon, and a set of marks was created to achieve sub-micron alignment between the two waveguides. Fabrication results showed that the coupler successfully transfers light between the two waveguides and that there is low loss in the polymer. A more accurate characterization of the coupler's efficiency was delayed due to fabrication problems not related to the developed process.
