We obtain conditions for the occurrence of polarization modulational instab
ility in the anomalous and normal dispersion regimes for the coupled nonlin
ear Schrodinger equation modelling fourth order dispersion effects when the
linearly polarized pump is oriented at arbitrary angles with respect to th
e slow and fast axes of the birefringent fiber.
