Abstract

Photonic crystal fiber (PCF) is a new type of optical fiber that adds a unique dimension to fiber design possibilities, enabling the previously unthinkable in fiber optics. The mode and the band-diagram analysis by conventional electromagnetic methods had proven the advantages of the PCF. When this new product couples to the existing optical fiber systems or vice versa, the important issue is the coupling efficiency. From among the available numerical techniques, the FDTD method seems to be the most reliable for such a task. The method does not force any assumptions on the behavior of the propagating light. It solves Maxwell’s equation in time domain and space domain directly and is readily applicable to problems like transmissions through refractive index discontinuities and multiple reflections on interfaces. The paper will present FDTD simulation results of the coupler and analysis of the calculated coupling efficiency on coupler design parameters.
