Abstract

Pushing the boundaries of cavity-enhanced spectroscopy experiments in the mid-IR is strongly tied to the availability of suitable mid-IR frequency combs and mirror coatings with well-characterized properties. Recently, substrate-transferred crystalline coatings (e.g. epitaxial GaAs/AlGaAs multilayers bonded on silicon substrates) have emerged as a groundbreaking new concept for the fabrication of high-performance thin-film interference coatings in the mid-IR, circumventing limitations of established material systems and physical vapor deposition technology. In this presentation, I will talk about state of the art, mid-IR frequency combs and present a detailed characterization of substrate-transferred crystalline mirrors centered at a wavelength of 4.55µm
