Description: This award is to support a collaborative project between Dr. Nadir Dagli, Department of Electrical and Computer Science at the University of California, Santa Barbara (UCSB) and Dr. Atilla Aydinli, Department of Physics, Bilkent University, Ankara, Turkey. The purpose of this research is to develop guided-wave polarization sensitive couplers and polarization converters in GaAs/AlGaAs material system, and eventually to use these components in the realization of polarization independent ultra fast traveling wave electrooptic modulators. Current work at UCSB has produced traveling wave electrooptic modulators with electric bandwidth in excess of 40 GHz. These modulators have relatively high switching voltages, excessive loss in coupling with optical fiber, and work only for TE polarization. The planned work will seek the production of devices with low switching voltage and low fiber coupling losses. The work proposed includes transfer of software developed at UCSB to the Bilkent team to use it in producing the modulator devices. These devices, and others produced at UCSB, will be subjected to optical tests such as loss measurements, and DC electrooptic tests such as the DC modulation response. Scope: This award allows for collaboration by two laboratories with complementary capabilities who are currently carrying out similar research independently. The award will allow visits by Dr. Dagli to Bilkent U. to provide the software and the required initial training and to help the Turkish scientist and a graduate student start the fabrication process. In the second year Dagli will again visit Bilkent U. to work on the testing process and to transfer the technology developed and the experience gained to his laboratory at UCSB. This award is funded jointly by INT and the Division of Electrical and Communication Systems.

描述：该奖项是为了支持加利福尼亚大学圣塔芭芭拉分校电气与计算机科学系Nadir Dagli博士（UCSB）（UCSB）和土耳其Bilkent大学物理系Atilla Aydinli博士之间的合作项目。 这项研究的目的是在GAAS/Algaas材料系统中开发带有指导的波化敏感敏感的耦合器和极化转换器，并最终将这些组件用于实现极化独立的超快速波动波电磁调节剂的实现。 UCSB的当前工作已经生产了电波电气调节器，电带宽超过40 GHz。 这些调节器具有相对较高的开关电压，与光纤连接过多损失，并且仅用于TE极化。 计划的工作将寻求生产具有低开关电压和低光纤耦合损耗的设备。 拟议的工作包括将UCSB开发的软件转移到Bilkent团队，以生产调制器设备。 这些设备以及在UCSB上生产的其他设备将经过光学测试，例如损耗测量值和直流电磁测试，例如DC调制响应。 范围：该奖项允许两个实验室的合作，并具有互补的能力，他们目前正在独立进行类似的研究。 该奖项将允许达格利博士访问Bilkent U.提供该软件和所需的初始培训，并帮助土耳其科学家和研究生开始制造过程。 在第二年，达格利将再次访问Bilkent U.从事测试过程，并转移开发的技术以及在UCSB实验室获得的经验。 该奖项由INT以及电气和通信系统的部门共同资助。
