Pulse-by-pulse near 800-nm band power stabilization using all-optical limiter based on self-phase modulation

We demonstrate a near 800-nm range all-optical limiter to stabilize pulse-by-pulse peak power fluctuations of near 800-nm optical pulses. The all-optical limiter proposed here relies on intensity-dependent spectral pattern change by self-phase modulation (SPM) under zero-dispersion condition by using a photonic crystal fiber (PCF). The experimental result shows the successful output power stabilization less than 0.36 dB against the 2.0 dB input power fluctuation.
