| Résumé | Directional couplers are extensively used devices in integrated optics, but suffer from limited operational wavelength range. Here we use, for the first time, the dispersive properties of sub-wavelength gratings to achieve a fivefold enhancement in the operation bandwidth of a silicon-oninsulator directional coupler. This approach does not compromise the size or the phase response of the device. The sub-wavelength grating based directional coupler we propose covers a 100nm bandwidth with an imbalance of =0.6dB between its outputs, as supported by full 3D FDTD simulations. © 2012 Optical Society of America. |
