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 As 2 S 3 strip waveguides on an existing QCL chip. Integrated As 2 S 3 strip waveguides constructed in this manner display strong optical confinement and guiding around 90 ° bends, with a NA of 0.24 and bend loss of 12.9 dB at a 1 mm radius ( λ = 4.8 μm ).
