Enhanced surface emission in terahertz quantum cascade lasers using plasma layer assisted photonic crystal waveguides
Introduction:Surface-emitting terahertz quantum cascade lasers (THz QCLs) are highly promising for applications requiring high-quality far-field beams and controlled beam divergence. However, limited brightness and output power in conventional surface-emitting designs remain significant barriers to...
