Abstract
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.

Summary
Bistable laser diodes and amplifiers are expected to be key components for use in optical telecommunication networks (for a review see [1]). The output powers of the emitting parallel polarization mode and the subsidiary orthogonal polarization mode of the 1550nm-VCSEL have been simultaneously studied and this technique has led to the experimental observation of different shapes of PB in a 1550nm-VCSEL, including anticlockwise, clockwise and XShape or butterfly bistability, all of them with wide hysteresis cycles, up to four times wider with respect to previously reported results [8] This diversity of behaviour at 1550 nm, the most commonly used wavelength in optical telecommunication networks, offers promise for the use of VCSELs in optical signal processing and optical switching applications
