The polarization bistability (PB) features in a 1550 nm vertical-cavity surface-emitting laser (1550 nm-VCSEL) subject to variable polarization optical injection (VPOI) are experimentally investigated. We have investigated the influence of polarization angle $\theta _{p}$ of optical injection on PBs induced by scanning the power (power-induced PB) and the frequency of injected light (frequency-induced...
We investigate experimentally the state bistability driven by current or feedback in a 1550 nm vertical-cavity surface-emitting laser (1550 nm-VCSEL) with negative optoelectronic feedback (NOEF). The results show that through continuously varying the controlled parameters such as the bias current or the feedback strength along different routes, under a set of given system parameters, there may exist...
