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.

Download or read book Design and Fabrication of Optical Polymer Waveguide Devices for Optical Interconnects and Integrated Optical Coherence Tomography written by Guomin Jiang and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. 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.

Investigation of Optical Loss Changes in Siloxane Polymer Waveguides During Thermal Curing and Aging

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In high performance electronic systems, with increasing chip speed and larger number of processors, the system performance is being limited by off-chip metal interconnects. In such systems, polymer optical waveguides are being considered to replace electrical interconnects because of their high capacity for bandwidth and less constraints on interconnect length. The optical loss in the polymer optical waveguides is the key criterion used to evaluate their performance, and is significantly affected by thermal curing and aging. The evolution of degree-of-cure is determined from differential scanning calorimetry and compared to optical absorption from spectroscopy. Optical loss due to scattering mechanisms is related to local density fluctuations, which is studied using dielectric analysis. Based on the optical loss trends in uncladded and cladded waveguides, the underlying mechanisms for the optical loss variations are proposed and a cure process schedule to realize the lowest optical loss is recommended. Process-induced thermal stresses can also affect the polymer waveguide by introducing stress birefringence. The stress-optical coefficients of the siloxane polymer are extracted and employed in a numerical modeling method to determine the stress-induced birefringence in an optical waveguide system. The thermal-aging dependent optical loss is determined for waveguide samples at several different accelerated temperature conditions. To get the field-use conditions, the temperature distribution in the vicinity of the embedded laser and the polymer waveguide is determined. Using such thermal experimental data, the analytical reliability models were employed to relate the optical loss with time, and provide a practical way of determining whether the optical waveguides would perform within the optical loss budget during field-use conditions.
