Abstract
We present the latest advances on terahertz quantum-cascade vertical-external-cavity surface-emitting-lasers (VECSELs) that are designed for wide tuning of a single-mode (up to 25% fractional tuning). The enabling component is the amplifying reflectarray metasurface, which allows lasing in Fabry-Perot cavities on very low-order longitudinal modes.
