Abstract

We present the realization of active photonic crystal terahertz lasers operating in higher photonic bands. The resonator consists of an array of isolated pillars which are embedded in a metallic waveguide. These devices reduce the overlap with gain region and increase the effect of the surrounding medium. Thereby, it is either possible to directly manipulate the lasing mode or to sense variations in the environment.
