We demonstrate numerically that efficient and lasting squeezed light can be achieved due to a constructive two-photon interference. Even if large phase fluctuations occur, the dispersion in one of the two quadrature components of the light field can still be reduced below the standard quantum limit set by the symmetric distribution of the vacuum state. Experimental observation of squeezed light in this system is possible by generalizing the recent techniques of Ou’s group [L. J. Lu and Z. Y. Ou, Phys. Rev. Lett. 88, 023601 (2002)].
