Abstract

Vacuum fluctuation, which is the intrinsic nature of an electric field, can be measured via homodyne detection. Moreover, electric field intensity fluctuations are also related to vacuum fluctuations. Squeezed vacuum and sub-Poisson light can be obtained by controlling the vacuum fluctuation using noble nonlinear interaction. Based on the squeezed vacuum, by inserting a mirror on the unused part of the beam splitter was proposed in (Youn SH, Lee JH, Chang JS, in International Workshop on Squeezed States and Uncertainty Relations, N95-13921 (1994)), we present the mode-matching method for the vacuum and light fields. Light intensity fluctuations also can be reduced by inserting a mirror on the unused part of the beam splitter. To obtain sub-Poisson light as a function of the distance between the mirror and detector, a detector with a thinner active layer than the wavelength is required.
