Due to their strong light conﬁnement, waveguides with optical nonlinearities may be a promising platform for energy-eﬃcient optical computing. Slow light can enhance a waveguide’s eﬀective nonlinearity, which could result in devices that operate in low-power regimes where quantum ﬂuctuations are important, and may also have quantum applications including squeezing and entanglement generation. In this manuscript, slow-light structures based on the Kerr (χ(3)) nonlinearity are analyzed using a semi-classical model to account for the quantum noise. We develop a hybrid split-step / Runge-Kutta numerical model to compute the mean ﬁeld and squeezing spectrum for pulses propagating down a waveguide, and use this model to study squeezing produced in optical waveguides. Scaling relations are explored, and the beneﬁts and limitations of slow light are discussed in the context of squeezing.
