摘要
本文利用SO(3)旋转群性质得到了非线性双折射介质模型的一个严格解.由此证明相干态进入双折射介质后将产生宏观上可分辨的量子迭加态.为检测它们所产生的干涉条纹,本文采用零拍检测方案,计算了初态为线偏振和圆偏振相干光时零拍检测器输出流的几率分布.
An exact solution for the nonlinear birefringent medium model is obtained by using SO(3) rotation group property. It is proved that coherent light entering the medium will evolve into a superposition of maorosoopioally distinguishable quantum states. In order to detect their interference fringes, holodyne detection scheme is used and the probability distribution for the output of homodyne detector is calculated when the intial states being linear and circular polarization coherent light.
