Figure 1

The schematic illustration of dual-channel spike encoding based on VCSEL-SA. TL1 and TL2: tunable laser; Mod1 and Mod2: modulator; PPG1 and PPG2: pulse signal generator; PC: polarization controller; VOA: variable optical attenuator; FC: fiber couple; OC: optical circulator; VCSEL-SA: vertical-cavity surface-emitting laser with an embedded saturable absorber; PBS: polarization beam splitter; PD1 and PD2: photodetector. The solid (dashed) lines correspond to optical (electrical) path.
