The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Photonics for microwave measurements (2016, methodology): “Currently, photonic-assisted microwave channelizers have been developed based on space-division multiplexing (SDM) [83,84], wavelength-division multiplexing (WDM) [85–99], and time-division multiplexing (TDM) [100–103].”
A microwave channelizer and spectroscope based on an integrated optical Bragg-grating Fabry-Perot and integrated hybrid Fresnel lens system (2006, background): “These devices, however, are limited in resolving power [9], cascaded power loss in reflection [10], interferometer limitations [11], complex optical post-tuning steps [12]–[14], and bulky classical optical implementation [15], [16].”
Broadband RF Channelizer Based on an Integrated Optical Frequency Kerr Comb Source (2018, methodology): “physically split for spectral channelizing, were achieved via diffraction gratings [12], acousto-optic crystals [13], fiber gratings [14], and integrated devices [15].”
Broadband Photonic RF Channelizer With 92 Channels Based on a Soliton Crystal Microcomb (2020, unknown): “tered narrow-linewidth filters [12]–[15].”
