Real-time compensation of single photons polarization state drift based on genetic algorithm
- 13 Downloads
We present an automatic single photons polarization state control system. The single photons polarization state optimizing results are theoretically simulated based on genetic algorithm. With the optimized integration time, single photons polarization state drift is experimentally compensated using the four-channel polarization controller manipulated by genetic algorithm. The intensity fluctuation is less than 3% for an arbitrary input polarization state transformed into the stable output polarization state.
