Quantum-cascade micro-lasers with Bragg-mirrors operating up to 315 K have been realized. Due to the large mode spacing in short cavity lasers and the limited gain bandwidth, single mode emission in such devices is possible.

We have demonstrated the ability to selectively modify the mode structure of multi-moded photonic crystal laser cavity. As a result, in this case an improved side-mode suppression ratio was obtained.

We present polarization-stable InGaAs/GaAs VCSELs with up to 6 mW single-mode output power. The orientation of their polarization along the [011],[0~11] [010] or [001] crystal axis is defined and controlled by a dielectric grating relief.

We have developed GaN-based high-power blue-violet laser diodes with a small aspect ratio for beam divergence by optimizing the optical confinement in the active layer. A small aspect ratio of 1.3 and a high output power of 200 mW with kink-free operation have been achieved.
