We present an on-chip nonlinear optics based correlated and higher dimensional state photon source using silicon hybrid materials. The four-wave mixing process occurring in a ring resonator is used to generate a frequency comb of signal and idler wavelengths corresponding to different resonant wavelengths around the pump resonance. The frequency comb based four-wave mixing process is used to generate higher-dimensional entangled photon pairs. The individual comb lines, into which the correlated photon pairs could be generated leads to higher dimensional entanglement. The ability to generate higher dimensional photon states is advantageous to pack more information for high data rate quantum communication and information processing applications.
