Noise Reduction in Microresonators using Feedback-Controlled Phase Modulation

Key Points

• To investigate how intrinsic noise affects the soliton repetition rate and explore methods to suppress it.
• Numerical simulations were conducted to assess noise impact on soliton behavior.
• Phase modulation was applied to the pump using its photodetected RF output.
• The architecture was designed for compact, chip-compatible implementation.
• Phase modulation significantly reduced the impact of intrinsic noise on soliton repetition-rate.
• Effective noise suppression was achieved in a chip-compatible framework.
• Results indicate enhanced stability in soliton operations under varying noise conditions.
