In this paper, we present new structures based on ring, conventional photonic crystal and hybrid PhC for enhanced Raman amplification. The structures consist of two separate entrances for the pump and signal. In this way, only pump is coupled into the ring and signal passes through the amplified pump without creating coupling noise. Using engineered nano holes filled with optofluidic materials in the signal and pump paths, we reduce pump and signal group velocity to improve the structure and achieve larger Raman gain and less dispersion. The time evolution and propagation of picosecond signal pulses and dispersion inside the device are analyzed and Raman gain, Raman bandwidth and bit rate are studied in one-ring and two-ring structures. To model Raman amplification in these structures, Maxwell equations are solved using finite difference time domain method considering optical nonlinear parameters like two photon absorption, free carrier absorption and Kerr effect.
