A multifluid infiltrated input/output coupler for efficient light transmission from a slow hole-type hexagonal photonic crystal waveguide (PCW) was designed based on the optofluidic technique. The structure of is similar to regular PCW, with little difference in two innermost rows, which are filled different fluids. This allows experience step-by-step change its group velocity as it reaches and passes central PCW. Simulation results reveal improvement more than 75% use three-fluid compared conventional inserted directly efficiency about 10%.
