Electrically controllable silicon-based photonic time lens. a Measured transmission spectra at the drop-port of the fabricated ET-MRR with different DC voltages applied on the microelectrode. b The output spectrum of the optical frequency comb generator. Inset: original flat optical frequency comb (green) and optical filter of wave shaper (purple). c Driving electrical signal (mixed split sawtooth signal and DC signal) of the ET-MRR. d The time-resonance wavelength curve of the time lens is calculated
