Abstract

We demonstrate low-loss chalcogenide ( As 2 S 3 ) waveguides on a LiNbO 3 substrate for the mid-IR wavelength ( 4.8 μm ). Designed for single-mode propagation, they are fabricated through photolithography and dry-etching technology and characterized on a mid-IR measurement setup with a quantum cascade laser. For straight waveguides, propagation loss as low as 0.33 dB / cm is measured and low-loss bends on the order of 100 μm are simulated, with measurement results showing < 3 dB for a 250 μm bend radius. The coupling efficiency is estimated to be 81%. In addition, the influences of variations in width and bend radius are also investigated.
