In this project, compact wavelength detectors for multiwavelength opto-electronic integrated circuits (multiwave OEICs) were developed. Performances of the proposed devices were evaluated to analyze the impact of wavelenght multiplexing for reducing communication subsystem complexity in parallel computing architectures.1. A compact wavelength detector using a dielectric multilayr thin-film (DMF) filter deposited on a silicon pn photodiode was designed and fabricated. DMF filter areas were successfully defined on a silicon substrate by employing lift-off technique using an evaporated Al film as a lift-off stencil. Finally, a one-chip wavelength detector array was implemented, demonstrating successful discrimination of four wavelength components within 635-830nm range.2. Fabrication of the proposed device structures will become increasingly difficult as the number of wavelengths in creases. To solve this problem, a new type of wavelength detector array employing a single DMF filter was proposed, and its performance was evaluated through computer simulation.3. The physical limit on the number of wavelength components that can be used in multiwave OEICs was examined. For example, assuming the width of waveguides, the thickness of DMF filters and the total gain bandwidth of lasers to be 20mum, 8mum and 100nm, respectively, it is estimated that eight wavelength components are available in the system. This number offers the potential for reducing area complexity of hypercube-based interconnection networks by the factor of 1/64 on an average. This demonstrates the impact of wavelength multiplexing for reducing communication subsystem complexity in future computers.

在该项目中，开发了用于多波长光电集成电路（多波OEIC）的紧凑型波长探测器。对所提出的器件的性能进行了评估，以分析波长复用对降低并行计算架构中通信子系统复杂性的影响。1．设计并制造了一种紧凑型波长检测器，该检测器使用沉积在硅 pn 光电二极管上的电介质多层薄膜 (DMF) 滤波器。通过采用剥离技术，使用蒸发的铝膜作为剥离模板，成功地在硅基板上定义了 DMF 过滤器区域。最后，实现了单芯片波长探测器阵列，成功区分了635-830nm范围内的四种波长分量。2．随着波长数量的增加，所提出的器件结构的制造将变得越来越困难。针对这一问题，提出了一种采用单DMF滤波器的新型波长探测器阵列，并通过计算机仿真对其性能进行了评估。 3．研究了多波 OEIC 中可使用的波长组件数量的物理限制。例如，假设波导的宽度、DMF滤波器的厚度和激光器的总增益带宽分别为20μm、8μm和100nm，则估计系统中可以使用八个波长组件。这个数字有可能将基于超立方体的互连网络的区域复杂性平均降低 1/64。这证明了波长复用对于降低未来计算机中通信子系统复杂性的影响。
