Abstract

Ring-based photonic crystal (PhC) structure for Raman amplifier is investigating in this article. Then using optofluidic materials in the holes on the sides of the signal path, pump and signal group velocity reducing that cause Raman gain increase. In order to achieve bigger Raman gain, we use two-ring structure. 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. Maxwell equations are solved by finite difference time domain (FDTD) method and considering the optical nonlinear parameters of two photon absorption, free carrier absorption, Kerr effect and self-phase modulation in PhC structure. From a structure with a length of 100 μm, Raman gain of 19.01 dB and bit rate of 0.6493 × 1012 pulse/sec are achieved.
