Abstract

We present the dispersion and Raman amplification characteristics of As 2 Se 3 photonic crystal fibers (PCFs). We compare the gain characteristics with conventional As 2 Se 3 fibers and find that the Raman gain efficiency in PCFs can be improved by a factor of more than 4. This allows us to either use a small length of the fiber or to use the low pump power to attain similar gain characteristics. Numerical simulations reveal that a peak gain of 10 dB can be achieved in a 1.1 m long PCF when it is pumped at 1.5 μ m in wavelength with an input power of 500 mW .
