Abstract :
Stable single mode operation of semiconductor lasers are of great interest for multi-giga bit long-span optical fiber communications. [1] Especially, quarter wave shifted (QWS-) DFB lasers are expected to be one of the most attractive light sources, because of their large threshold gain difference between a main mode and sub modes.
