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.

这里提出的研究延续了申请人领导的成功研究。迄今为止的工作已经在几个方向上进行。一个方向是用于光子网络的超高速集成光调制器领域，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组合的新型滤波器和滤波器系统的设计，还有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，一个重点将是在制造的设备中实现商业规格，而另一个重点将是纯粹的探索性，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的调制器设计，与目前使用的调制器相比，可以提高运行速度，减少片上面积，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。要研究的调制器将是利用反向偏置硅pn结中的“等离子体色散”效应的新型电折射型“推挽”装置。这项工作具有重要意义，因为在下一代和下一代光纤互连和电信系统中，将需要以拟议的速度（>40Gb/s）运行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方面的领先地位。在新型滤波器设计领域的工作目标将是实现在SOI平台上制造的电信质量（基于ITU-T建议书）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，我们最近展示了具有游标效应的双向光栅耦合级联磁道谐振器，该谐振器能够实现29 dB的间隙峰值抑制，并消除了滤波器在滴口的自由频谱范围。我们还演示了在降口处具有30db侧瓣抑制的基于bragg光栅的双向耦合器。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，还需要进一步改进。这项工作还将有助于加拿大保持其在电信相关技术方面的领先地位。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工业中的应用。光学传感器的高速、抗电磁干扰和非侵入性使其成为配电系统中设备监测的理想选择。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。这项工作意义重大，因为光学传感器在灵敏度、精度、带宽和电流隔离等方面比传统传感器有了重大改进。基于光纤的传感器在未来的输配电系统中扮演着重要的角色。这项工作将帮助加拿大在电力应用的光纤传感器开发方面保持领先地位。
