Topological bulk laser in kagome lattice

Stephan Wong and Sang Soon Oh

Not Accessible

Your library or personal account may give you access

Abstract

By introducing an imaginary gauge field, we demonstratet opologically pro-tected bulk modes extended over a two-dimensional kagome lattice with rhombus geometry. Using the kagome lattice with gain/loss, a phase-locked broad-area topological laser can be realized.
