In optical communication networks, an intensity fluctuation of optical signals is a serious issue, which is caused by and grows owing to transmission, amplification, and signal processing. Because it degrades the signal-to-noise ratio (SNR) of optical signals and eventually leads to inaccuracy of data, the intensity fluctuation of optical signals over optical communication networks must be compensated for. In order to compensate for the intensity fluctuation of optical pulses with a wide dynamic range, in this paper, we propose an ultrafast all-optical intensity stabilizer based on an intensity-dependent spectral pattern change and an optical pattern recognition. To verify the proposed method, we perform numerical simulations and experimental demonstrations. We confirm the basic operation of the optical intensity stabilizer through experimental demonstrations.
