Quadratures squeezing in Ti:LNB waveguide for the SHG process. Without the loss mechanism, the pump mode (blue-solid line) squeezes unboundedly, while the SH mode (magenta-solid line) is squeezed to half its initial value. When the loss mechanism is included, the squeezing rate of the pump mode (red-dashed line) is limited and the SH mode (cyan-dashed line) de-squeezes due to accumulated noises.
