Reconfigurable quasi-phase matching for field-programmable nonlinear photonics

摘要

A device, system, and method for in situ reconfigurable quasi-phase matching field-programmable nonlinear photonics that is reliably reconfigurable and maintains nonlinear conversion efficiency is presented. Devices include a ferroelectric waveguide susceptible to light-assisted poling; (UV-transparent) first electrode(s); one or more UV illumination sources; at least a second electrode; and a substrate. Reconfiguring the hybrid electronic/photonic field programmable array device includes selecting a device type; selecting parameters for the device; determining per-electrode voltages for the device; determining timing values for reconfiguring the device; initiating illumination of the device; applying per-electrode voltages of the device; terminating per-electrode voltages according to the timing values; and terminating illumination according to the timing values.
