We demonstrate narrowband orthogonally polarized optical radio frequency (RF) single sideband generation as well as dual-channel equalization based on an integrated dual-polarization-mode high-Q microring resonator. The device operates in the optical communications band and enables narrowband RF operation at either 16.6 or 32.2 GHz, determined by the free spectral range and TE/TM mode interval in the resonator. We achieve a very large dynamic tuning range of over 55 dB for both the optical carrier-to-sideband ratio and the dual-channel RF equalization.

They can greatly increase the capacity of communications systems and allow the processing of RF spectra for very wide range of advanced signal processing functions [113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132]”
Microcomb-Based Photonic RF Signal Processing (2019, methodology): “Based on these advantages, a wide range of RF applications have been demonstrated, such as optical true time delays [23]–[25], transversal filters [25]–[27], signal processors [28], [29], channelizers [30], [31] and others [32]–[34].”
High performance RF filters via bandwidth scaling with Kerr micro-combs (2019, methodology): “…between the comb spacing ( δ OFC ) and the FSR of the passive MRR ( δ PMRR ) for RF spectral channelizing, we used orthogonally polarization modes [38, 39] of the active and passive MRRs (TE mode of the active MRR, TM mode of the passive MRR) since they had slightly different effective indices —…”
