This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)Objective:The objective of this program is to devise and demonstrate architectures incorporating mode-evolution based, integrated polarization splitter and rotator devices in silicon photonics, in order to enable polarization sensing and manipulation functionalities on a silicon chip.Intellectual merit:Effects related to the polarization of light lead to significant issues in lightwave technology. One example is polarization-mode dispersion: optical pulses spread in time in a frequency- and polarization-dependent manner, leading to errors in telecommunications. While such effects can be compensated, the devices for sensing and manipulating polarizations are usually implemented in bulk optics, which limits their widespread application. Integrated devices are desirable for their strong size and cost advantages, especially if multiple devices can be integrated on a single chip to support wavelength-division multiplexing. Silicon photonics based, integrated polarization splitters and rotators enable polarization sensing, control and high speed modulation, thereby potentially offering a practical solution to compensate polarization mode dispersion, and also enable polarization multiplexing techniques, in which independent data is sent on two orthogonal polarization states to realize higher bit rate.Broader impacts:This work has the potential for significant impact by supporting advances in high-speed communications infrastructure pervasive to the economy. If successfully developed, integrated chips capable of polarization manipulation could pave the way to practical deployment of new optical compensators addressing serious distortion effects in fiber communications and enable new concepts for optical transmission systems and networks. Two Ph.D. students will be supported and one undergraduate student will be invited to participate.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金 目标：该计划的目标是设计和演示在硅光子学中结合基于模式演化的集成偏振分离器和旋转器器件的架构，以便在硅芯片上实现偏振传感和操纵功能。智力价值：与光偏振相关的效应导致光波中的重大问题 技术。一个例子是偏振模色散：光脉冲以频率和偏振相关的方式随时间传播，从而导致电信中的错误。 虽然这种效应可以得到补偿，但用于传感和操纵偏振的设备通常是在体光学器件中实现的，这限制了它们的广泛应用。集成器件因其强大的尺寸和成本优势而受到人们的欢迎，特别是如果多个器件可以集成在单个芯片上以支持波分复用的话。基于硅光子学的集成偏振分束器和旋转器可实现偏振传感、控制和高速调制，从而有可能提供补偿偏振模式色散的实用解决方案，并且还支持偏振复用技术，其中独立数据在两个正交偏振状态上发送以实现更高的比特率。更广泛的影响：这项工作通过支持高速通信基础设施的进步，有可能产生重大影响 普遍存在于经济中。 如果开发成功，能够进行偏振操纵的集成芯片可以为新型光补偿器的实际部署铺平道路，解决光纤通信中严重的失真效应，并为光传输系统和网络带来新的概念。两名博士学生将得到支持，并将邀请一名本科生参加。
