Within the last decade, research and development in the field of silicon microring resonators have been accelerated due to their potential in a wide range of applications. In this study, we experimentally characterize the selfpulsing dynamics in active silicon ring cavities under the effects of varying the optical power, detuning, and free-carrier lifetime. Self-pulsing is measured by coupling a single laser source into the microring resonator’s input port. The light collected from the output grating is fiber coupled and sent to a photodetector, oscilloscope, power meter, and optical spectrum analyzer (OSA) for both time and frequency domain measurement.
