Abstract: Optical transport networks are designed for high data rate transmission. To implement such a network it requires various passive components. The optical coupler is one of the important components of such a high capacity optical transport network. The coupling efficiency of coupler is wavelength sensitive and this degrades the performance of optical system that uses directional couplers for WDM transmission. A curved directional coupler has been proposed using silicon waveguides realizing the wavelength insensitive operation. The simulations are carried out using BeamPROP software and the effect on transmittance with respect to wavelength is analyzed. This curved coupler reduces the wavelength dependence
