Paper Abstract

Parity-time (PT) symmetry is a fundamental notion in quantum field theories and opens a new paradigm of non-Hermitian photonics. Instead of counteracting optical losses in integrated photonics, we start from an opposite viewpoint to strategically manipulate optical losses by the concept of PT symmetry. In this talk, I will discuss harnessing PT symmetry using the state-of-the-art integrated nanophotonics technology for novel optoelectronic functionalities. I will present unidirectional reflectionless light transport and coherent light control on a passive silicon platform and effective control of cavity resonant modes for stable lasing actions on an active III-V semiconductor platform.
