9906220 Unlu描述：该奖项是为了支持波士顿大学电气和计算机工程系塞利姆Unlu博士和土耳其安卡拉Bilkent大学物理系Ekmel Ozbay博士的合作项目。 两位研究人员计划进行研究，以1）研究在1.55微米波长下工作的高性能光电探测器，其带宽效率（BWE）产品接近100 GHz。 2)设计、制造和表征这些光电探测器。 所提出的探测器是基于谐振腔增强（RCE）检测方案的光学设计的顶照式光电二极管。 这项研究的最终产品将是光电探测器的带宽效率性能的重大改进，这将在长距离光通信系统中得到应用。范围：该奖项将允许土耳其和美国科学家之间的合作，他们具有互补的能力和经验。 计划中的合作将支持波士顿大学的研究计划，以扩大光电探测器的科学知识和经验，并生产一种新的光电探测器系列，其性能通过将有源器件结构放置在法布里-珀罗谐振微腔内来增强。 RCE检测方案可用于许多检测器设计中，以提高设备灵敏度和速度。 波士顿大学的两名研究生将参与这一合作项目。 这一提议符合INT在互利领域增加美国与外国合作的目标。

9906220UnluDescription: This award is for support of a cooperative project by Dr. Selim Unlu, Department of Electrical and Computer Engineering at Boston University and Dr. Ekmel Ozbay, Department of Physics at Bilkent University, Ankara, Turkey. The two investigators plan to conduct research to 1) study high performance photodetectors operating at 1.55 micrometer wavelength with bandwidth-efficiency (BWE) products approaching 100 GHz. 2) design, fabricate and characterize these photodetectors. The proposed detectors are top-illuminated photodiodes with optical design based on resonant cavity enhanced (RCE) detection scheme. The final product of this research will be a major improvement in the bandwidth efficiency performance of photodetectors, which will have applications in long-haul optical communication systems. Scope: This award will allow collaboration between Turkish and US scientists who have complementary capabilities and experience. The planned collaboration will support the Boston University research initiative to expand scientific knowledge and experience in photodetectors, and to produce a new family of photodetectors whose performance is enhanced by placing the active device structure inside a Fabry-Perot resonant microcavity. The RCE detection scheme can be used in many detector designs to improve the device sensitivity and speed. Two graduate students at Boston University will participate in this collaborative project. This proposal meets the INT objective of increasing US-foreign collaboration in areas of mutual benefit.
