Abstract
We have investigated the squeezing and statistical properties of the light
cavity coupled to a vacuum reservoir via a single-port mirror. We carry out our
analysis by considering the vacuum reservoir to be a noiseless physical entity
and by applying the large-time approximation scheme to the quantum Langevin
equations.
We have found that the mean photon numbers of light modes and are the
same in the absence of spontaneous emission and the mean photon number of
light mode is greater than that of light mode in the presence of spontaneous
emission. Our analysis also shows that mode is in general in chaotic state
while mode is in a chaotic state under certain conditions. It is also found that the
superposed light modes are in squeezed state with a maximum quadrature
squeezing of 43% for = 0 and 46.5% for = 0.1 below the coherent vacuum
state level
