Abstract

We developed vertical emitting THz QCL sources having an optical resonator based on a quasi-periodic patterning of the top metal layer of a double-metal waveguide. The designed pattern induces a distributed feedback effect capable of providing optical feedback as well as vertical extraction in a sharply collimated far field.
