Abstract :
We report the first use of focused ion beam milling to fabricate surface relief gratings in optical waveguides. We demonstrate efficient coupling to very high order modes in silicon-on-insulator waveguides and discuss the implications both for future devices based on higher order modes as well as more conventional devices based on Bragg reflection from the fundamental mode.
