Simulation-guided design of an integrated photonic cavity for frequency-multiplexed Spontaneous Parametric Down Conversion
The study simulates a frequency-multiplexed Spontaneous Parametric Down Conversion (SPDC) cavity using a racetrack resonator design. The simulation successfully yielded 90 doubly resonant signal/idler frequency-mode pairs with high efficiency, demonstrating the design's capability to produce narrow bandwidths and specific spectral characteristics required for quantum networking applications.
