Free Space to Single Mode Fiber Coupling Efficiency Improvement Using Wave-Front Sensor-Less Adaptive Optics

We demonstrate that a wave-front sensor-less adaptive optics system based on SPGD algorithm improves fiber coupling efficiency by 2.0 dB, 5.6 dB and 12.1 dB under weak, moderate and strong turbulence, respectively.
