Huge bistabilities at high optical injection level

This work shows that at high injected power (> 0 dBm), huge bistable area (extending over 11 dB and 35 GHz) for a slave laser operating at four times its threshold (the optical output power is equal to 5 dBm). Moreover, for moderate injected power (-10 dBm), that are usually presented in the literature, the authors observe multistability that has been already predicted.
