Abstract
We have proposed and analyzed receiver architecture for an optical differential quadrature phase-shift-keying (oDQPSK) based on micro-ring resonator (MRR) filter discriminator and direct detection. The simulation results confirm that such an MRR based receiver provides considerable tolerance to chromatic dispersion as well as the nonlinear self-phase modulation (SPM) effect compared to the receiver architectures based on delay interferometer as well as the Gaussian filter type demodulators.
