Abstract

We demonstrate a bit-rate-variable differential phase-shift keying (DPSK) demodulator based on silicon microring resonators (MRRs) with an integrated diode for wavelength tuning. The resonance wavelength of the MRR may be tuned by carrier injection and depletion. Error-free operations (bit error rate <;10^-9) have been achieved for all tuning wavelengths. In addition, the proposed scheme can demodulate DPSK signals over a wide range of bit rates from below 25 to 40 Gb/s.
