The Mid-IR wavelellgth range is particularly interesting for spectroscopic sellsing applicaJiOIiS.
Inregration of Quantum Cascade Lasers with a photonic integrated circuit will pave the way for providing a tunable laser source along with a possibility of Lab-oll-achip applications. A major challenge in reaJi~ation of these devices is identification of
a suitable waveguide platform. [n this paper we will discuss the design andjabrication strategies of the possible waveguide platforms and will propose a generic concept of realizing a widely tunable integrated QCL using wavelength selective feedback elements implemented on a silicon photonic chip.
