Abstract

Topological photonics attracts attention as a fundamental framework for robust manipulation of light. Combined with an optical gain, active topological cavities hold special promise for a design of high-performance nanolasers. In this talk, we present two types of novel topological resonant modes, multipolar lasing modes from topological corner states and ultralow-threshold lasing modes using super-bound states in the continuum, for the demonstration of low-threshold lasing.
