EFFECT OF GUIDED ACOUSTIC-WAVE BRILLOUIN-SCATTERING ON PULSED SQUEEZING IN OPTICAL FIBERS WITH NONLINEARITY AND DISPERSION

Quadrature squeezed light generation with optical pulses in a fiber lo op mirror is analyzed through computer simulation. The effect of guide d acoustic wave Brillouin scattering (GAWBS) in optical fibers as well as those of nonlinearities and chromatic dispersions are considered f or the first time. The relation between the GAWBS noise and the optica l pulse width is discussed in detail. It is found that the nearly fund amental soliton pulse is optimum to get the largest squeezing even ii the GAWBS noise is effective. The broadened pulses suffer larger degra dation of squeezing due to this noise.
