Abstract

A planar waveguide design is presented that integrates As₂S₃ chalcogenide glass with Ti-diffused lithium-niobate (LN) waveguides to increase functionality. As₂S₃ is a higher index material that is introduced to create small bend radii structures that are crucial for making high density optical circuits. As₂S₃ waveguide patterns are aligned on top of the straight LN waveguide. Power launched into LN is coupled to the higher index As₂S₃ cladding structure and propagates through a tight bend before coupling back to the LN waveguide. Experimental results are given for s-bends of 2.48cm minimum radius of curvature.
