Dual core photonic crystal fiber (PCF) couplers that support femtosecond (fs) pulses have been presented in this paper. The couplers are dispersion managed and relatively short. A vector finite-element-based model has been developed to precisely evaluate coupling coefficients and higher order dispersions for wavelength selective applications of these PCFs. Material dispersion of silica glass along with the waveguide dispersion has also been taken into account. Cladding has been designed innovatively to manage coupling length and dispersion. Dispersion demonstrates the wavelength region where it can support short duration pulses, and the propagation of 100 fs pulses has been shown at 1550 and 1310 nm wavelengths, respectively, incorporating the higher order dispersions and wavelength selective coupling behavior.
