Directional couplers are widely used as one of the key component of optical integrated circuits. However, the coupling ratio of the conventional directional coupler is highly sensitive to wavelength, and it degrades the characteristics of the devices that are consisted of directional couplers for WDM (Wavelength Division Multiplexing) transmission. The curved directional coupler has been proposed using silica optical waveguide as one of the coupler which realize wavelength insensitive, small footprint and tolerant to fabrication. In this work, we theoretically investigated this curved coupler using Si photonic wire waveguide and got results that this curved coupler whose bending radius of 21$mu$m and the coupling length of 7.40$mu$m can reduce the wavelength dependence and achieve about 3.3 fold enhancement of the operational bandwidth in wavelength range of 1.5$mu$m-1.6$mu$m compared with the conventional directional coupler. |
