  We report on the generation of nonclassical states of light in a silicon ring
resonator in a selfpumping scheme. The ring is inserted in a lasing cavity, for
which it acts as a filter, so that the lasing always occurs within a selected
ring resonance, without active stabilization of the resonance frequency. We
show the emission of coincident photon pairs and study their correlation
properties through the reconstruction of the measurements via stimulated
emission.
