Multi-mode THz quantum-cascade VECSELs based on disordered metasurfaces Open
Quantum-cascade vertical-external-cavity surface-emitting-lasers (VECSELs) based on disordered amplifying metasurfaces are demonstrated and explored as potential broadband, multi-mode THz sources. The disorder is introduced along one spati…
