광증폭기에서 수직 편광된 두 펌프 빔을 사용한 4광파 혼합 신호 생성

초록

We have studied photon pair generation by using the four-wave-mixing (FWM) in a semiconductor optical amplifier (SOA) for potential use as an entangled photon source in quantum cryptography. Our scheme uses the non-degenerate FWM effect with two pump beams of orthogonal polarizations and one signal beam. The efficiency and maximum output power of the generated FWM signals are measured.
