Study of generation of optical frequency combs using microring resonators and its application to optical clock rate multiplication

This work concentrates on the application of spectrally periodic filtering nature of microring resonators for optical clock/pulse rate multiplication. This is a less complex, low cost route for realization of high bandwidth optical communication systems. Microring resonator is modeled theoretically to extract appropriate dimensions and cross coupling ratios to realize spectral filtering with different periodicities. Using this, a 5X multiplication of a 10GHz optical pulse stream to generate 50GHz optical clock has been theoretically demonstrated.
