Quadrature-phase squeezing by optical parametric amplification in an arbitrary photonic crystal was studied by use of a perturbation theory based on a Green function formalism. It is shown that the perturbative calculation can be performed to an infinite order. The result shows that quadrature-phase squeezing is enhanced by small group velocities of electromagnetic eigenmodes that are easily achieved in two- and three-dimensional photonic crystals.
