Photonic Integrated Circuits and Devices

一项为期三年的研究计划被授予开发单片集成偏振调制激光器，该激光器可以被调制到超高频和耦合激光器，可以作为光学双稳元件用作开关、存储器和逻辑电路。该方案的一个独特特点和基本主题是，在最终适合大规模集成的制造方法的背景下，对器件概念进行测试和评估。具体任务包括：a.构建与半导体激光器集成的电光TE-TM模式转换器，形成偏振调制激光器；b.演示半导体激光器在20至100 GHz范围内的自控和外控偏振调制；C.建立耦合半导体激光器，以演示双模双稳定性，并表征这些器件的开关速度和开关能量；D.开发基于单片可积双稳半导体激光器的光门和子系统；e.进一步改进用于制造单片集成光电器件和电路的化学辅助离子束刻蚀（CAIBE）方案。

A three-year research program is awarded to develop monolithically integrated polarization-modulated lasers that can be modulated to ultra-high-frequencies and coupled lasers that can function as optical bistable elements for use as switches, memories, and logic circuits. A unique feature and basic theme of the proposed program is that the device concepts are tested and evaluated in the context of a fabrication approach that is suitable for large scale integration eventually. specific tasks include: a. To build an electro-optic TE-TM mode converter for integration with a semi-conductor laser to form a polarization-modulated laser; b. to demonstrate self and externally- controlled polarization modulation of semiconductor lasers in the 20 to 100 GHz range; c. to build coupled- semiconductor lasers to demonstrate two-mode bistability and to characterize the switching speed and switching energy of these devices; d. to develop optical gates and subsystems based upon monolithically integrable bistable semiconductor lasers; e. further improvement of chemically-assisted ion-beam etching (CAIBE) scheme for fabricating monolithically integrated optoelectronic devices and circuits.
