This book was released on 2014-08-26 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the detailed investigation of stress-induced birefringence in polymer optical waveguides and demonstrates an approach for the potential design of polarization-insensitive waveguide devices considering such stress-effects. To estimate the stresses accurately, it presents a process-modeling framework in the Finite Element analysis, which can incorporate important stress build-up processes, such as polymerization shrinkage, stress relaxation, and etching, over the entire history of the waveguide fabrication process. It also presents the characterization of the stress-optic and thermo-optic coefficients of polymers in thin film waveguide. Being generic in nature, the described approach enables the optimized design of various integrated optical devices from the standpoint of material systems, waveguide geometry, and process parameters. This book is expected to lay the groundwork for the researchers on the management of stress related problems in integrated optical devices and photonic packaging.

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 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.

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 Analysis of a Poled polymer Electro optic Modulator with a Strip loaded Waveguide Structure written by Antonio Arthur Davis and published by . This book was released on 2010 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: To fully utilize the advances of electro-optic (EO) polymer research, a detail design and model of a triple stacked poled-polymer, electro-optic waveguide modulator was developed to provide guidance in the selection of cladding layers and demonstrate how the mode conditions affect the overall device performance. Waveguide devices depend not only on the EO materials used in the core, but also on the cladding materials. In contrast to most of the research that has focused on molecular engineering of the electro-optically active materials to improve the core properties of the waveguide, this work studied the effects of cladding material properties to improve overall device performance of an electro-optic waveguide modulator. Various, commercially available polymer materials were identified and investigated for potential cladding layers according to their optical, electrical, process ability and film casting properties. A poled-polymer, strip-loaded waveguide, EO modulator is designed and analyzed in terms of single mode conditions, optical loss due to the metal electrodes, modulation efficiency, and mode size. Two designs were compared: Design 1 optimized the half-wave voltage for a single-arm modulator (Vpi = 2.5 V) with a nearly symmetric waveguide by maximizing modulation efficiency and minimizing the overall thickness of the waveguide; Design 2 optimized the insertion loss (6 dB) with a strongly asymmetric waveguide by maximizing the overall mode size to most efficiently overlap with a single mode fiber. High frequency analysis of a microstrip electrode showed a modulator with a push-pull scheme can be fabricated with half-wave voltage (Vpi) of 4.0 V for Design 1 and 5.1 V for Design 2 at 3 GHz. Some general guidelines in the design of a poled-polymer electro-optic modulator incorporating a strip-loaded waveguide structure are suggested. First, the core layer thickness and ridge width supporting single mode propagation should be fabricated as large as possible by increases the asymmetry of the refractive index between the top and bottom cladding layer. Second, the thicknesses of the top and bottom cladding layers must be optimized through an analysis of the waveguide mode amplitude distribution so that the electrode-associated optical loss is minimized to a required level while simultaneously the total thickness of the waveguide is minimized. The ridge structure greatly simplifies fabrication procedures, reduces fabrication steps and eliminates propagation losses due to roughness of etched sidewalls. The results of the analysis were modeled in beam propagation software to confirm the ideal conditions for single mode propagation.
