Abstract
We propose a new reflector approach in order to get the reflectivity c omb needed in widely tunable lasers. This reflector is realized by hol ographic exposure of superimposed multiple Bragg gratings, It provides efficient reflectivity with short guide sections (150 mu m) leading t o improved static laser characteristics. This reflector has been succe ssfully included in 20-nm tuning DBR lasers.
