Abstract
We demonstrate on-chip hybrid integration of chalcogenide glass waveguides and quantum cascade lasers (QCLs). Integration is achieved using an additive solution-casting and molding method to directly form strip waveguides on an existing QCL chip. Integrated strip waveguides constructed in this manner display strong optical confinement and guiding around bends, with a NA of 0.24 and bend loss of at a radius ().
