Cheng Peng—Dynamically programmable surfaces for high-speed optical modulation

Описание: Cheng Peng, a recent PhD graduate from Electrical Engineering & Computer Science (EECS) gave the Nano Explorations talk on Thursday, July 2, 2020.

Dynamically programmable surfaces for spatiotemporal control of light are crucial to many optoelectronic technologies including high-speed optical communication, display and projection, autonomous driving, optical information processing, imaging, and optical control in quantum computation. Currently available electro-optic spatial light modulators (SLMs) are often bulky, inefficient, and have limited operation speeds.

This talk describes the development of a compact, high-speed, electro-optic SLM architecture based on a two-dimensional array of tunable microcavities. Optimized microcavity designs can enable high-speed, high diffraction efficiency SLMs with standard-CMOS-compatible driving voltages. High-speed electro-optic material options are discussed.

Nano Explorations is a virtual seminar series powered by MIT.nano that features presentations by MIT students on their work in nanoscience, nanotechnology, and other advanced research fields. The series was launched as a way to keep our nano community connected during the COVID-19 pandemic. Presentations take place on Tuesdays and Thursdays at 11am EST and are open to any interested viewers.
