Field-enhancing tapered planarized waveguides for THz quantum cascade laser frequency combs

We present a new planarized waveguide geometry for THz quantum cascade laser frequency combs with improved waveguide losses, RF and thermal dissipation properties. Ridge devices display broadband free-running comb states, and the THz emission can be further broadened by RF injection. Tapered wavegui...
