Laser and Detection System for Topological Light Sources
Abstract
Recently, a new class of photonic devices has emerged that use topological physics to control the flow of light. A key manifestation of topological physics is the emergence of unidirectional edge modes that are confined to the boundary of a system and are remarkably robust against local disorder. Topologically-protected photonic edge states have now been experimentally demonstrated in a variety of systems including coupled ring resonators coupled waveguides,metallic and dielectric metamaterials, nanophotonic crystals, and at diverse frequency scales including, microwaves, tera-hertz, near IR and visible optical frequencies. Furthermore, topological edge states have enabled a plethora of applications, such as robust optical delay lines, reconfigurable photonic devices, topological beam-splitters, topological lasers, etc. In this DURIP proposal, we propose to upgrade our capabilities to realize novel phases of photonic higher-order topological insulators using synthetic dimensions coupled via nonlinear processes and generate quantum states of light using corner states in our integrated topological photonic devices. In particular, we plan to purchase a picosecond pulsed, broadband tunable laser system at telecom wavelengths to efficiently enhance nonlinear interactions and a cryogenic superconducting nanowire detector system for detection of quantum states of light, a tunable filter, and a waveshaper for reducing noise in our measurements.
