Bistability in two-mode semiconductor lasers via gain saturation

Abstract: The conditions required to achieve bistability in two-mode semiconductor lasers via the nonlinearity associated with gain saturation are discussed. The laser can be switched between the bistable states through coherent or incoherent optical control. Wavelength bistability in such a laser is demonstrated experimentally.

“…The bi-stability of active-MMI BLDs is mainly based on cross-gain saturation between two identical propagation paths in the same cavity [15][16]. Extremely wide hysteresis windows have been realized by utilizing the bi-stability of the lowest two lateral mode paths (0 th and 1 st order mode paths) in asymmetric active-MMI configurations, as shown in Fig.…”

“…We expanded the model suggested by Van Campenhout et al [1] for several modes and included self and cross gain suppression with the corresponding factors ε S and ε C [8][9][10]. A parabolic gain curvature was assumed to account for the non-uniform gain spectrum [11].…”

“…In addition, scattering due to sidewall roughness causes a coupling of the counter-propagating modes which is modelled by k int [12]. The external injection coupling factor k ext models the coherent external injection [9] of light into the respective lasing mode. Table I lists the values of the parameters used in the model.…”
