2D patch antenna array on a double metal quantum cascade laser

Matthias Justen, Christopher Bonzon, Keita Ohtani, Mathias Beck, Urs U. Graf, and Jérôme Faist (2016)

Overview

We developed patch array antennas for Terahertz quantum cascade lasers (QCLs) to improve the optical quality of the beams emitted by the devices. The design also includes an outcoupling reflector which can be adapted to the optimum reflectivity for a given laser.
