Novel microwave photonic applications based on integrated microcombs (Invited)
Fig. 1. Microcomb-based low-phase-noise microwave generation. (a)-(c) Single-sideband phase noise of 10 GHz microwave signals generated respectively with MgF2 toroid cavity[2], SiN microring[3], and SiO2 wedge cavity[4]. The insets show the microcavity photos. The five lines in (a) indicate the phase noise in different cases: (1) without filter, (2) with filter, (3) induced by thermal noise, (4) induced by quauntum noise, (5) background of phase noise analyzer
Fig. 2. Microcomb-based microwave photonic signal processing. (a) Single-passband and reconfigurable microwave photonic filter based on microcomb spectral shaping[5]; (b) Tunable microwave photonic filter based on soliton crystal microcombs[6]; (c) Reconfigurable microwave photonic filter based on microcomb bandwidth scaling[7]; (d) Microwave photonic channelizer based on microcomb and linear microcavity filter[8]
Fig. 3. Microcomb-based microwave true-time-delay beamforming[9]. (a) Microcomb spectrum; (b) Microwave beam pattern corresponding to (a)
