Abstract :
In this letter, we describe the properties of broadband single-sided and double-sided transmissive tilted gratings for LP/sub 10/-to-LP/sub 11/ mode coupling. Some of the tilted gratings show nearly complete coupling over a 30-nm wavelength range, and appreciable coupling over a spectral width as wide as 160 nm. Coupling properties of single-sided and double-sided tilted gratings agree well with coupled mode theory predictions.
