We have measured optical power and wavelength polarization bistability in a 1550 nm-Vertical Cavity Surface-Emitting Laser (VCSEL) subject to orthogonally-polarized optical injection into the orthogonal polarization of the fundamental transverse mode. Optical bistability with very wide hysteresis cycles, up to four times wider than previously reported results has been measured for both the optical power and wavelength domain. We also report the experimental observation of three different shapes of polarization bistability, anticlockwise, clockwise and X-Shape bistability, all of them with wide hysteresis cycles. This rich variety of behaviour at the important wavelength of 1550 nm offers promise for the use of VCSELs for all-optical signal processing and optical switching/routing applications.
我们测量了一个1550纳米垂直腔面发射激光器（VCSEL）中的光功率和波长偏振双稳性，该激光器受到向基横模正交偏振方向的正交偏振光注入。在光功率和波长域都测量到了具有非常宽滞后回线的光学双稳性，其宽度比先前报道的结果宽达四倍。我们还报告了对三种不同形状偏振双稳性（逆时针、顺时针和X形双稳性）的实验观测，它们都具有宽滞后回线。在重要的1550纳米波长处这种丰富多样的行为为将VCSEL用于全光信号处理及光开关/路由应用带来了希望。
