Broadband THz quantum cascade laser frequency combs with surface emission and inverse-designed facet reflectors
We present a planarized waveguide cavity with an integrated broadband output coupler that improves both the output power and far-field properties of THz quantum cascade laser frequency combs. The laser mirror reflectivity can be tuned by the shape of the end facet, which is obtained with an efficien...
