| Abstract: | Quadrature squeezed light generation with optical pulses in a fiber loop mirror is analyzed through computer simulation. The effect of guided acoustic wave Brillouin scattering (GAWBS) in optical fibers as well as those of nonlinearities and chromatic dispersions are considered for the first time. The relation between the GAWBS noise and the optical pulse width is discussed in detail. It is found that the nearly fundamental soliton pulse is optimum to get the largest squeezing even if the GAWBS noise is effective. The broadened pulses suffer larger degradation of squeezing due to this noise. |
