Parametric Gain Calculation in Photonic Crystal Fiber

Signal wave parametric gain was calculated in photonic crystal optical fiber. Photonic crystal fiber structure was optimized for broadband parametric gain. It is shown, that gain bandwidth for photonic-crystal fiber optical parametric amplifier could be more than 400 nm. Spectral changings in parametric gain due to modulation of photonic crystal waveguide cross-section was studied.
