Abstract

This paper summarizes our research work on optoelectronic devices with nanostructures. It was indicated that by manipulating so called “general energy-bands” of fundamental particles or quasi-particles, such as photon, phonon, and surface plasmon polariton (SPP), novel optoelectronic characteristics can be obtained, which results in a series of new functional devices. A silicon based optical switch with an extremely broadband of 24 nm and an ultra-compact (8 mm × 17.6 mm) footprint was demonstrated with a photonic crystal slow light waveguides. By proposing a nanobeam based hetero optomechanical crystal, a high phonon frequency of 5.66 GHz was realized experimentally. Also, we observed and verified a novel effect of two-surface-plasmon-absorption (TSPA), and realized diffraction-limit-overcoming photolithography with resolution of ~1/11 of the exposure wavelength.

Biography

Yidong Huang received her B.S. and Ph.D. degrees in optoelectronics from Tsinghua University, Beijing, China, in 1988 and 1994, respectively. From 1991 to 1993, she was with Arai Laboratories, Tokyo Institute of Technology, Japan, on leave from the Tsinghua University. Her Ph.D. dissertation was mainly concerned with strained semiconductor quantum well lasers and laser amplifiers. In 1994, she joined the Photonic and Wireless Devices Research Laboratories, NEC Corporation, where she was engaged in the research on semiconductor laser diodes for optical-fiber communication and became an assistant manager in 1998. She received “Merit Award” and “Contribution Award” from NEC Corporation in 1997 and 2003, respectively. She joined the Department of Electronics Engineering, Tsinghua University in 2003, as a professor, and be appointed by the Changjiang Project and the National Talents Engineering in 2005 and 2007, respectively. She was Vice Chairman of the Department from 2007-2012 and has been the Chairman of the Department from 2013. She is presently engaged in research on nano-structure optoelectronics.

Prof. Huang authored/co-authored more than 300 journal and conference papers. She is a senior member of the IEEE.
