摘要:【中文】本发明涉及一种全光、宽频、低噪声偏振旋转门的实现方法。利用一种相干制备的原子系统与一束强泵浦光和一束线偏振弱信号光相互作用,可使得该原子系统变成电磁诱导透明(EIT)系统和主动拉曼增益(ARG)系统的组合系统。利用两波混频效应,EIT系统产生的吸收与ARG系统产生的增益互相抵消,使得该相干制备原子系统具有很多优良性能。例如,信号光可在很宽的频域内实现损失/增益接近于零,原子系统中的噪声被显著抑制等。在此基础上再加入相位控制光,利用交叉克尔效应,可使得线偏振弱信号光经过原子系统后偏振方向旋转90°,从而实现偏振旋转门。 【EN】The invention relates to a method for realizing a full-optical, broadband and low-noise polarization revolving door. By utilizing the interaction of a coherently prepared atomic system and a beam of strong pump light and a beam of polarized weak signal light, the atomic system can be changed into a combined system of an Electromagnetic Induced Transparency (EIT) system and an Active Raman Gain (ARG) system. By using the two-wave mixing effect, the absorption generated by the EIT system and the gain generated by the ARG system are mutually counteracted, so that the coherent preparation atomic system has a plurality of excellent performances. For example, signal light can achieve loss/gain close to zero in a wide frequency domain, noise in an atomic system is significantly suppressed, and the like. On the basis, phase control light is added, and the polarization direction of the linearly polarized weak signal light can be rotated by 90 degrees after passing through an atomic system by utilizing the cross Kerr effect, so that the polarization rotating door is realized.
