Abstract
Reconfigurable nonlinear frequency conversion waveguide chip based on Mach-Zehnder interferometer coupled micro-ring, the method is based on the integration of waveguide components of phase-adjustable Mach-Zehnder interferometers (MZI) and micro-ring resonators. The chip is illustrated by FIG. 1. The MZI couples light and photons into and output of the micro-ring resonator and controls the micorings' quality factor thus optimize the nonlinear frequency conversion processes inside the ring by the phase-modulator inside the MZI. The micro-ring resonator enables the nonlinear optical generation of new frequency light beams and quantum light sources based on the second-order or third-order nonlinear optical process. Other optical waveguide components in region I and III of FIG. 1 are linear optical circuits for power splitting of pump beams and post-process of generated light beams or photons.
