AI 中文摘要
本文从理论上分析了在半导体放大器中，饱和光放大过程中产生压缩量子态光的可能性。由于放大过程中的四波混频效应，介质自发辐射中相对于强放大波具有对称频移的弱分量获得了双模压缩光的量子特性。正交分量的压缩发生在几GHz（约等于载流子密度弛豫时间的倒数）的频移范围内，在最优条件下可达10 dB或更高。双模压缩相位的形成有利于观测压缩效应，其中强波作为本地波，在无需额外零差探测的情况下表现出正交噪声抑制。
英文摘要
The possibility of generating light in a squeezed quantum state during saturated light amplification in a semiconductor amplifier is theoretically analyzed. Due to four-wave mixing process during amplification, weak components of the spontaneous emission of the medium with symmetric frequency shifts relative to the strong amplified wave acquire the quantum properties of two-mode squeezed light. The squeezing of quadrature components occurs in the range of frequency shifts of several GHz ($\sim$ the inverse relaxation time of the charge carrier density) and can reach 10 dB or more under optimal conditions. The formation of a two-mode squeezing phase facilitates the observation of the squeezing effect, in which a strong wave, playing the role of a local wave, exhibits quadrature noise suppression without additional homodyne detection.
