Abstract
We present a broadband planarized THz quantum cascade laser with inverse-designed waveguide facets, coupled to a broadband patch array antenna for surface emission. We measure an emission spectrum spanning 800 GHz, a peak power of 13.5 mW and a symmetric far-field pattern with a narrow beam divergence of (21° x 20°) . Show more
