Tuneable QCL

Designing a tuneable Quantum Cascade Laser for mid-infrared frequency operation.

Thermal SPhPs

Investigation of thermally excited surface phonon polaritons in nanostructured polar dielectric materials.

Extended cavity quantum cascade laser with cavity resonator integrated grating filter

We demonstrate our design of a stable tuneable quantum cascade laser with extremely narrow operational frequency that can be tuned digitally.

Mid-infrared cavity resonator integrated grating filters

Here we design, fabricate, and experimentally study Cavity Resonator Grating Filters that are used to design a tuneable QCL in mid-infrared frequency range.
