Abstract
A Distributed Feedback waveguide with a diffraction grating on the Si/CaF2 heterostructurewaveguide is proposed for near-and mid-infrared applications. In this study, we focused on a Si-based quantum cascade laser structures. Simulation of the waveguide operating at a bragg wavelength of 1.70 [µm] shows that arbitrary transmittance and reflectance can be obtained by changing the grating conditions.
