Silicon on insulator components for optical data transmission systems.

提出的研究继续成功研发(R)，应用有三个截然不同的研究方向。一个方向涉及用于光网络的光调制器。另一个方向与新型过滤器和过滤系统的发展有关。另一个方向涉及用于光网络的紧凑型、基于亚波长光栅和亚波长光栅辅助的基本光学组件的开发。所有这些工作都将用于在SOI平台上制造的光学系统和子系统。*面积调制器的工作目标是研究新型调制器设计，与目前使用的SOI调制器相比，可以提高工作速度、减少片上占地面积、降低功耗和控制线性调频。这种调制器的发展将促进未来光学互连和电信系统的进一步发展，并显著降低其成本。被研究的调制器将在硅pn结中使用“等离子体色散”效应。超低功率、自由光谱范围自由(FSR-Free)、低啁啾、基于微环谐振器(MRR-Based)的调制器以及基于超低啁啾、推挽、无FSR、基于MRR的干涉型调制器和超低啁啾、推挽偏振调制器将被研究。*新型滤波器设计领域的工作目标是针对数据通信和/或电信应用。这些滤光器将使用MRR、光栅、反向耦合器以及谐振器、光栅和/或反向耦合器的组合。这些将是紧凑的基于MRR的滤波器，具有弯曲的反向耦合器，在直通和下降端口都具有抑制的自由光谱范围和大的相邻边模抑制比。其他将被研究和进一步开发的滤光器是超紧凑的、变迹的、串联堆叠的、基于反向耦合器的滤光器，用于课程波分复用应用。*开发用于光网络的紧凑型、基于SWG的和SWG辅助的光学组件的工作目标将集中在诸如基于模式演变的耦合器、可调谐耦合器、偏振旋转器、偏振组合器、偏振分离器、偏振分离器-旋转器、偏振旋转器-组合器、可调谐偏振转换器、偏振旋转滤光器、偏振独立器件、谐振器、振荡器、这项工作意义重大，因为这样的设备应该为标准的、商业上可用的制造工艺提供更大的性能一致性。*这项建议旨在确保加拿大在商业上可用的SOI平台的组件设计和开发方面保持领先地位，从而总体上处于与光子学相关的研发的前沿。

The research proposed continues successful research and development (R The application has three distinct research directions. One direction is related to optical modulators for use in optical networks. Another direction is related to the development of novel filters and filter-systems. Yet another direction is related to the development of compact, sub-wavelength-grating-based and sub-wavelength-grating-assisted, fundamental optical components for use in optical networks. All of the work proposed will be intended for use in optical systems and subsystems fabricated on SOI platforms.******The objective of the work in the area modulators is to research novel modulator designs that increase operating speed, reduce on-chip real estate, lower power consumption, and control chirp, as compared to SOI modulators currently in use. The development of such modulators will facilitate the further development of, and significantly reduce the cost of, future optical interconnects and telecommunication systems. The modulators to be investigated will use the "plasma-dispersion" effect in silicon pn junctions. Ultra-low power, free-spectral-range-free (FSR-free), low-chirp, micro-ring resonator-based (MRR-based) modulators will be investigated as will ultra-low chirp, push-pull, FSR-free, MRR-based interferometric modulators and ultra-low chirp, push-pull polarization modulators.******The objective of the work in the area of novel filter designs is targeted at datacom and/or telecom applications. These filters will use MRRs, gratings, contra-directional couplers, and combinations of resonators, gratings, and/or contra-directional couplers. These will be compact MRR-based filters with bent contra-directional couplers having suppressed free-spectral-ranges and large adjacent side-mode-suppression-ratios at both the through and the drop ports. Other filters that will be investigated and further developed are ultra-compact, apodized, series-stacked, contra-directional-coupler-based filters for course wavelength division multiplexing applications.******The objective of the work into the development of compact, SWG-based and SWG-assisted optical components for use in optical networks will focus on fundamental components such as mode-evolution-based couplers, tunable couplers, polarization rotators, polarization combiners, polarization splitters, polarization splitter-rotators, polarization rotator-combiners, tunable polarization converters, polarization rotating filters, polarization independent devices, resonators, etc. This work is significant in that such devices should offer greater performance uniformity for standard, commercially available, fabrication processes.******This proposal is aimed at ensuring that Canada remains at the forefront of the design and development of components for commercially available SOI platforms and, therefore, at the cutting edge of photonics related R&D in general.
