Design of PIC devices for generating coherent optical lattice in a 2D slab region.

Abstract

We explore the use of inverse design methods for generation of periodic optical patterns in photonic integrated circuits. A carefully selected objective function based on the integer lattice method, which is an algebraic technique for optical lattice generation, is shown to be key for successful device design. Furthermore, we present a polychromatic pattern generating device that switches between optical lattices with different symmetry and periodicity depending on the operating wavelength. Important links are drawn between optical coherent lattices and optical potentials, pointing towards practical applications in the fields of quantum simulations and computing, optical trapping, and bio-sensing.

Software implementation

The source code used to generate the optical lattices in the paper are in the jupyter notebook (can be viewed directly on GitHub).
