Blind source separation of chaotic laser signals by independent component analysis.
We experimentally demonstrate blind source separation of chaos generated in Nd:YVO(4) microchip solid-state lasers by using independent component analysis. Two chaotic source signals are linearly mixed with randomly selected mixing ratio and independent component analysis is applied for the mixed signals to extract the source signals. We investigate blind source separation of many chaotic laser signals and succeed 100-signal separation of chaotic temporal waveforms. Longer temporal waveforms are required with increase of the number of mixed signals.
