Bright sub-Poissonian light generation with a balanced nonlinear Sagnac interferometer (SI) is demonstrated. A balanced SI is transformed into a phase-sensitiver amplifier by injecting a coherent-state input signal, which can be either amplified or deamplified depending on its phase relative to that of the pump. A novel technique based on two orthogonally polarized pulses in both the pump and the signal interferometer arms compensates for guided-acoustic-wave Brillouin scattering (GAWBS) noise. This GAWBS cancellation scheme is proven viable and practical in achieving squeezing in fibers.
