Compact Bends for Achieving Higher Integration Densities for LiNbO3 Waveguides Academic Article

abstract

• A new waveguide platform is demonstrated that allows the bend radii to be substantially decreased for titanium- diffused lithium-niobate (LiNbO3) waveguides using vertically integrated arsenic-trisulfide (As2S3) overlay waveguides. Power is transferred from a Ti-diffused waveguide into the overlay waveguide using tapers, guided by the As2S3 waveguide through the S-bend region and transferred back into another Ti-diffused waveguide. This structure also behaves like a polarization beam splitter. We present simulation results as well as measurements to show the feasibility of achieving low loss and reduced bend radii for electrooptic waveguides. 2009 IEEE.
