【摘要】 利用多模压缩态理论,研究了多模泛函偶相干态的等幂次振幅压缩特性,结果发现:当压缩次数为奇数时,两正交相位分量可呈现互补对称的等幂次振幅压缩效应,其压缩程度、压缩深度及压缩幅度与压缩次数、态间叠加几率幅、各模的经典强度和经典相位的空间分布函数等强烈地非线性关联.进一步研究发现,对由经典强度为基模高斯分布的两个三模光场构成的多模泛函偶相干态,其压缩特性与理论分析结果并不完全相同.更多还原

【Abstract】 By utilizing the theory of multimode squeezed state,the characteristics of generalized nonlinear equal-power amplitude squeezing of the multimode functional even coherent state is studied,and it is found, when the squeezed number is an odd number,the two quadrature components of the state can present symmetry equal-power amplitude squeezing effect,the squeezed degree,the squeezed depth and the squeezed amplitude are related intensively to the squeezed number,the superposition probability, the classical intensity and initial phase of each mode of the state and other parameters.The further research shown that the conclusions are not completely the same as the theoretical results if the classical intensity of the two three light-fields of the multimode functional even coherent state according to ground mode circular Gaussian distribution.更多还原
