Abstract

In this work, we present and discuss that pillar type photonic crystal lasers provides, along with spectral control of the light, lower losses, broader single mode tuneability and higher operating temperature than a state of the art fabricated FP cavity. Also in-plane emitting properties at 3 THz, we show that the quantum cascade laser emission can be achieved in surface direction at 1.5 THz with PhC band structure engineering.
