✦ Synopsis

In this work we demonstrate an interesting opportunity to decrease drastically the group velocity of light in two-dimensional photonic crystals constructed form materials with large dielectric constant without dispersion (3 d w100). The group velocity of light in the crystals can be lowered up to 10 K5 -10 K4 c (c is velocity of light in free space) in a wide range of the Brillouin zone. We propose a simple and general explanation why that should appear in photonic crystals with large dielectric constants.

## Abstract Optical amplification is demonstrated in a slab photonic crystal waveguide (PCW). Nonlinear dispersive gain FDTD and traveling‐wave rate equation method (TWRE) are used to design a photonic crystal semiconductor optical amplifier (PC‐SOA). Optical amplification based on slow light of PC
