Topological insulator lasers — •Mordechai Segev — Technion - Israel Institute of Technology

Topological Insulator Lasers are arrays of semiconductor lasers arranged on a photonic chip in a way that endows them with topological features. We utilize the topological features of robustness and nonzero group velocity, both associated with the topological edge states, to force injection locking of tens of semiconductor lasers, eventually giving rise to many lasers working together as a single high order radiation source. The concepts of topological insulator lasers will be reviewed, while current challenges and recent progress will be described.
