Query: Dynamics of laterally-coupled pairs of spin-VCSELs   A newly-developed normal mode model of laser dynamics in a generalised array
of waveguides is applied to extend the spin-flip model (SFM) to pairs of
evanescently-coupled spin-VCSELS. The effect of high birefringence is explored,
revealing new dynamics and regions of bistability. It is shown that optical
switching of the polarisation states of the lasers may be controlled through
the optical pump and that, under certain conditions, the polarisation of one
laser may be switched by controlling the intensity and polarisation in the
other.
