Semiconducting Materials for Photonic Technology

Abstract

Semiconducting materials are important photonic materials and the technologies developed have been utilized in many fields of the modern society and they are closely related to the quality of our life. The main applications of the materials are for light source and sensing originated from interaction of photons and matters. In this invited talk, I will first present our work on the properties of the semiconducting materials and their applications as lasers and photodetectors, and then present integrated hybrid subwavelength structures which show significant enhancement on device performance. It is believed that complex hybrid structures which combine quantum-and hetero-structures made of semiconducting materials, and subwavelength structure for performance enhancement are the main focus in the near future.
