Abstract :
The authors report the transfer of six Bragg gratings at the same location into semiconductor material. Measurements on an active device demonstrate that all the gratings have the same efficiency for guided light. This technology is an attractive alternative to the sampling effect for providing multiwavelength filter functionality at predefined wavelengths
