Micro-resonator devices and optical broadband access application

Integrated photonic micro-resonators have attracted a great deal of attention in recent years, and various types of devices are demonstrated for communication and signal processing applications. In this paper, we present some of our recent work on silicon-based microring modulators, demodulators and chromatic dispersion compensators. Signal generation in on-off-keying and differential phase-shift-keying data formats is shown, while microring filters are used to carry out the demodulation of the phase-modulated signals. We also describe how to use only two ring resonators, by combining an under-coupled one with an over-coupled one, to form an on-chip single-channel dispersion compensator.
