Integrated waveguides

We implement solution processes to make mid-IR waveguides from chalcogenide glass. In contrast to etching-based methods, our solution-casting technique enables fabrication of microns-thick structures that match quantum cascade laser dimensions for on-chip integration. This technology leads the way to realizing compact and low-cost mid-IR laser-integrated devices for advanced chemical sensing.
