Abstract

We have for the first time experimentally demonstrated an ultrasmall, low power penalty, and robust 10 - Gb/s differential-phase-shift-keying demodulator using a silicon-based microring resonator. The microring resonator is compatible with a wide range of signal bit rates. In optical transmission measurements with 11.6-km nonzero dispersion-shifted fiber, the microring resonator demodulator had comparative power penalty compared with a Mach-Zehnder delay interferometer both in single ended detection. Error-free detection was achieved.
