Spatial and Spectral Mode-Selection Effects in Topological Lasers with Frequency-Dependent Gain
Matteo Seclì, Tomoki Ozawa, Massimo Capone +1
We develop a semiclassical theory of laser oscillation into a chiral edge state of a topological photonic system endowed with a frequency-dependent gain. As an archetypal model of…

Theory of chiral edge state lasing in a two-dimensional topological system
Matteo Seclì, Massimo Capone, Iacopo Carusotto
We theoretically study topological laser operation in a bosonic Harper-Hofstadter model featuring a saturable optical gain. Crucial consequences of the chirality of the lasing edge…
