We present experimental results of output power bistability in a vertical-cavity surface-emitting laser under optical injection induced by frequency detuning or power variation of the master laser. An ultra-wide hysteresis cycle of 3.7 nm (473.3 GHz) is achieved through frequency detuning, which is more than 11 times wider than that achieved in the state-of-the-art (37 GHz). Furthermore, the width of injection power induced hysteresis cycle we achieved is as large as 7.3 dB. We theoretically analyzed the hysteresis cycles based on standard optical injection locking rate equations including the interference effect of master laser reflection and found excellent agreement with experimental results.

    • "In recent years, considerable interest has been turned to the long wavelength (1300-1550nm) VCSELs, especially at the important telecom wavelength of 1550 nm because of its potential application in long haul data fiber-based communication. So far, the polarization output characteristics of 1550 nm VCSELs with optical injection have been investigated and PS phenomenon can be obtained [24]–[26]. More recently, we have experimentally investigated the nonlinear dynamics of 1550nm VCSELs with positive optoelectronic feedback [27] or optical feedback [28], and the two-mode coexistence phenomenon has been preliminarily observed.

    ABSTRACT: Two-mode coexistence in 1550-nm vertical-cavity surface-emitting lasers with optical feedback is experimentally investigated in detail. With the increase of the feedback strength, the two-mode coexistence region is enlarged for continually varied current. The feedback delay time has little influence on the two-mode coexistence region distribution under our experimental conditions. Moreover, a mapping of polarization-mode suppression ratio between two linear polarization (LP) modes is presented in the parameter space of the bias current and the feedback strength. In addition, the simultaneous chaos outputs of two LP modes are obtained for a certain two-mode coexistence region. Index Terms— 1550nm vertical-cavity surface-emitting laser (1550nm VCSEL), two-mode coexistence, optical feedback.

    ABSTRACT: A bidirectional chaos communication system, composed of 1550nm semiconductor lasers (SLs) and fiber links, is experimentally and numerically investigated. Based on the robust chaos synchronization between two authorized SLs, 0.5Gbits/s pseudo-random data bidirectional message transmission between the two SLs has been preliminarily realized experimentally. Moreover, related theoretical simulations are also given, which basically conforms to our experimental observations.

    ABSTRACT: Polarization switching (PS) between two orthogonal linearly polarized fundamental modes is experimentally observed in commercial free-running 1550 nm vertical-cavity surface-emitting lasers (VCSELs) (Raycan). The characteristics of this PS are strongly modified after introducing a polarization-preserved (PP) or polarization-orthogonal (PO) optical feedback. Under the case that the external cavity is approximately 30 cm, the PP optical feedback results in the PS point shifting toward a lower injection current, and the region within which the two polarization modes coexist is enlarged with the increase of the PP feedback strength. Under too-strong PP feedback levels, the PS disappears. The impact of PO optical feedback on VCSEL polarization behavior is quite similar to that of PP optical feedback, but larger feedback strength is needed to obtain similar results.
