Optical self-pulsing oscillations in passive silicon microring resonator on doped PN junction

In this work, we demonstrated experimentally the self-pulsing oscillations in silicon microring resonators (MRRs) with a frequency of 8 MHz. These oscillations are controlled by varying the optical power and detuning. This generated oscillation, with a microwave frequency range, can serve as a microwave oscillator to generate stable, high-frequency signals.
