Abstract

Soliton switching in nonlinear directional couplers implemented in photonic crystal fibers (PCF) examined here. A vector finite element method (FEM) has been developed to precisely calculate the dispersion along with coupling length of the guided modes. The PCF coupler geometry was carefully designed so that it can support soliton pulses. Soliton switching is demonstrated numerically at 1.55 mu m for 100 femto-second (fs) pulses. Our theoretical results explain some of the key spectral features previously observed in the experiment. (C) 2008 Optical Society of America.
