标题： Squeezing and Dual Recycling in Laser Interferometric Gravitational Wave Detectors

摘要： 我们计算了结合双回收和压缩光的理想迈克尔逊干涉仪对引力波的响应。 光子计数噪声来自通过输入端口送入的光以及由引力波在边带频率处产生的真空模式。 最小可检测引力波振幅取决于波的频率以及压缩和回收参数。 压缩和双回收的宽带操作都能降低光子计数噪声，因此这两种技术可以一起使用以进行更精确的相位测量。 发现光子数的方差是时间相关的，在引力波频率下振荡，但其幅度远低于常数部分。 显示英文摘要

摘要： We calculate the response of an ideal Michelson interferometer incorporating both dual recycling and squeezed light to gravitational waves. The photon counting noise has contributions from the light which is sent in through the input ports as well as the vacuum modes at sideband frequencies generated by the gravitational waves. The minimum detectable gravity wave amplitude depends on the frequency of the wave as well as the squeezing and recycling parameters. Both squeezing and the broadband operation of dual recycling reduce the photon counting noise and hence the two techniques can be used together to make more accurate phase measurements. The variance of photon number is found to be time-dependent, oscillating at the gravity wave frequency but of much lower order than the constant part.
