The research proposed here continues successful research led by the applicant. The work to date has been in several directions. One direction is in the area of ultrahigh-speed, integrated-optic modulators for use in photonic networks, another direction is in the design of novel filters and filter-systems based on ring resonators, gratings, and combinations of ring resonators and gratings, and yet another direction is the design of novel photonic sensors. The devices proposed will, primarily, be fabricated on the Silicon-On-Insulator (SOI) platform. The work has two thrusts, one thrust of the work will be to achieve commercial specifications in the devices fabricated while the other thrust will be purely exploratory and aimed at developing novel device and system architectures.**The objective of the work in the area of ultrahigh-speed modulators is to research novel modulator designs that increase operating speed, reduce on-chip real-estate, and lower power consumption, as compared to modulators currently in use, and that facilitate the development of next generation and generation-after-next fiber-optic interconnects and telecommunication systems. The modulators to be investigated will be novel electro-refraction type "push-pull" devices using the "plasma-dispersion" effect in reverse biassed silicon pn junctions. This work is significant in that modulators operating at the speeds proposed (>40Gb/s) and requiring low drive powers will be needed in next-generation and in generation-after-next fiber-optic interconnects and telecommunications systems. Modulators with both interferometric and polarimetric outputs will be explored. This work will help Canada maintain its position as a leader in telecommunications in telecommunications related technologies.**The objective of the work in the area of novel filter design will be to achieve telecom quality (based on ITU-T Recommendations) filters fabricated on the SOI platform. These filters will be fabricated using resonators, gratings, and combinations of resonators and gratings. For example, we have recently demonstrated contra-directional grating-coupled cascaded racetrack resonators exhibiting the Vernier effect capable of achieving interstitial peak suppressions of 29 dB, and eliminating the free-spectral-range of the filter, at the drop port. We have also demonstrated apodized, Bragg-grating-based contra-directional couplers with 30 dB side-lobe-suppression at the drop-port. Nevertheless, further improvement is needed before these filters will be ready for implementation in wavelength-division-multiplexed systems, or dense-wavelength-division-multiplexed, systems. This work will also help Canada maintain its position as a leader in telecommunications in telecommunications related technologies.**The objective of the work in the area of optical sensors is to expand the application of integrated-optic sensors and sensor systems within the power industry. The high-speeds, immunity to electromagnetic interference, and non-intrusive nature of optical sensors make them ideal for use in equipment monitoring in power distribution systems. Such sensors will facilitate more efficient power delivery and the production of high-quality power that is demanded in a modern, deregulated industry. This work is significant in that optical sensors offer major improvements over conventional sensors in areas such as sensitivity, accuracy, bandwidth and galvanic isolation. Fiber-optics-based sensors have a large role to play in future power transmission and distribution systems. This work will help Canada remain at the forefront of fiber-optics-based sensor development for power utility applications.

这里提出的研究继续由申请人领导的成功研究。 到目前为止，这项工作是在几个方面进行的。 一个方向是在用于光子网络的超高速集成光学调制器领域，另一个方向是基于环形谐振器、光栅以及环形谐振器和光栅的组合的新型滤波器和滤波器系统的设计，并且又一个方向是新型光子传感器的设计。 所提出的器件将主要在绝缘体上硅（SOI）平台上制造。 这项工作有两个重点，一个重点是在制造的设备中实现商业规格，另一个重点是纯粹的探索性，旨在开发新的设备和系统架构。超高速调制器领域的工作目标是研究新型调制器设计，与目前使用的调制器相比，这些调制器设计可以提高工作速度，减少片上不动产，降低功耗，并促进下一代和下一代光纤互连和电信系统的发展。 所研究的调制器是利用反向偏压硅pn结中的等离子体色散效应的新型电折射型推挽器件。 这项工作的重要性在于，在下一代和下一代光纤互连和电信系统中将需要以所提出的速度（> 40 Gb/s）操作并且需要低驱动功率的调制器。 将探讨具有干涉和偏振输出的调制器。 这项工作将有助于加拿大保持其在电信相关技术领域的领先地位。**在新的滤波器设计领域的工作的目标将是实现电信质量（基于ITU-T建议）的SOI平台上制造的滤波器。 这些滤波器将使用谐振器、光栅以及谐振器和光栅的组合来制造。 例如，我们最近展示了反向光栅耦合级联跑道谐振器，其表现出的游标效应能够实现29 dB的间隙峰值supperiment，并消除了滤波器的自由频谱范围，在下降端口。 我们还展示了变迹，布拉格光栅为基础的反向耦合器与30分贝旁瓣抑制在下降端口。 然而，在这些滤波器准备好用于波分复用系统或密集波分复用系统之前，需要进一步改进。 这项工作还将帮助加拿大保持其在电信相关技术领域的领先地位。**光学传感器领域的工作目标是扩大集成光学传感器和传感器系统在电力行业中的应用。 光学传感器的高速性、抗电磁干扰性和非侵入性使其成为配电系统设备监控的理想选择。 这种传感器将促进更有效的电力输送和高质量电力的生产，这是现代放松管制的行业所需要的。 这项工作是重要的，因为光学传感器在灵敏度，准确性，带宽和电流隔离等领域提供了比传统传感器更大的改进。 基于光纤的传感器在未来的输电和配电系统中发挥着重要作用。 这项工作将帮助加拿大保持在电力公用事业应用的光纤传感器开发的最前沿。
