An efficient method of all-optical buffering with ultra-small core photonic crystal fibers.
We propose a new method of all-optical buffering with ultra-small core photonic crystal fibers (PCFs) based on stimulated Brillouin scattering. The large refractive index contrast between the near-hollow cladding and the pure-silica core contributes to high nonlinearity of the PCF. Considering the unusual gain spectrum of the ultra-small core PCF, we numerically investigate the influence of these factors to the buffering efficiency. A PCF with a length of 1 meter and a core diameter of 1.06 micrometer is simulated as the storage medium in this paper. It is shown that we can obtain a good buffering efficiency under a very low control power of 2 watt, which promises a significant improvement for the all-optical communication system.
