Abstract

We present the dispersion and Raman amplification characteristics of ${\mathrm{As}}_2{\mathrm{Se}}_3$ photonic crystal fibers (PCFs). We compare the gain characteristics with conventional ${\mathrm{As}}_2{\mathrm{Se}}_3$ 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 $10\mathrm{dB}$ can be achieved in a $1.1\mathrm{m}$ long PCF when it is pumped at $1.5\mu \mathrm{m}$ in wavelength with an input power of $500\mathrm{mW}$.
