Abstract:
We theoretically propose a scheme to enhance the photon indistinguishability of spectrally mismatched single photons via Floquet-engineered optical frequency combs in cavity quantum electrodynamic systems. By periodically modulating two distinct single-photon states under a modulation frequency which is exactly equal to the spectral mismatch of two cavity modes, a pair of single-photon frequency-comb states is prepared energy-conservatively based on full unitary operations. The two states show high indistinguishability with an ideal g_{HOM}^{(2)}(0) down to zero due to the superposition of intensity-matched single-photon states coherently distributed across the teeth of the combs.
