  We present a system of four ring resonators capable of generating
programmable polarization and frequency-bin entangled photon pairs on an
integrated photonic device. Each ring is pumped with a continuous wave,
generating photon pairs with the same polarization in two pairs of frequency
bins via spontaneous fourwave mixing. We show that the density operator of the
generated state represents a hyperentangled state in the polarization and
frequency bin degrees of freedom. We also calculate the generation rate of the
state.
