We are presenting the development of a nonlinear diffusion model to aid the design and fabrication of annealed proton-exchanged (APE) channel waveguides in zirconium-doped lithium niobate (Zr:LiNbO3 or Zr:LN). This work follows research at Stanford by Bortz [1, 8] and Roussev [2], who developed nonlinear diffusion models for congruently melting LiNbO3 (CLN).
Single photon sources based on a self-assembled quantum dot in nanophotonic waveguides, gratings, and cavities are interfaced with nonlinear media and electro-optic modulators to demonstrate quantum frequency conversion and amplitude modulation of single photon states.
We demonstrate how transformation optics can be used to amplify optical gradient forces. We show how meta-materials allow to enhance optical forces between waveguides over several orders of magnitude, even when realistic losses are included.
