Ring quantum cascade lasers with twisted wavefronts
We demonstrate the on-chip generation of twisted light beams from ring quantum cascade lasers. A monolithic gradient index metamaterial is fabricated directly into the substrate side of the semiconductor chip and induces a twist of the light’s wavefront. This significantly influences the obtained be...
