Abstract
A theoretical analysis of optical frequency combs associated with the main and suppressed linear polarization modes of a gain-switched long-wavelength VCSEL is performed. We have studied the VCSEL polarization-resolved dynamics by using an extension of the spin-flip model to include nonlinear carrier recombination. Our results show that two orthogonally polarized combs are generated that combine to produce a wider overall optical comb. The dependence of combs on the VCSEL parameters and on the amplitude and frequency of the modulation is analyzed. Bistability between the two orthogonally polarized combs is found.
