a Optical microscopy image of an MRR with a bending radius of 60 μm. b Single-cycle demonstration of one distinct non-volatile state. c Measured transmissions at the through port of the MRR-based PZT optical memristor with different setting voltages Vset. d Measured resonance-wavelength detuning of the MRR-based PZT optical memristor set with different setting voltages Vset as the driving voltage Vdr varies. e Eye diagrams for NRZ modulation at the data rate of 48 Gbps with a driving voltage Vdr of 3 V.
