Chalcogenide ring mid-infrared sensor (CHARMS)
Abstract
The overall proposed objective is to explore and develop a novel chalcogenide-based sensor with low loss and high nonlinearity for detection of chemical and biological molecules in the 3-5 microns wavelength range. The chalcogenide material is the enabling factor that is proposed to be exploited in the proposed research. Chalcogenide films will be thermally evaporated, allowing freedom of substrate choice. Standard fabrication techniques such as e-beam and deep UV lithography, combined with lift-off, will be used to make the waveguides and resonators. Device performance will be limited mainly by interface scattering, which scales very favorably with wavelength. The proposed chalcogenide platform is not predicted to suffer from multiphoton absorption effects and can be evaporated on a wide variety of substrates.
