Self-trapping and stable localized modes in nonlinear photonic crystals
We predict the existence of stable nonlinear localized modes near the band
edge of a two-dimensional reduced-symmetry photonic crystal with a Kerr
nonlinearity. Employing the technique based on the Green function, we reveal a
physical mechanism of the mode stabilization associated with the effective
nonlinear dispersion and long-range interaction in the photonic crystals.Comment: 4 pages (RevTex) with 5 figures (EPS
