摘要：

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