A new distributed Bragg reflector laser for improved tuning

We propose a new distributed Bragg reflector laser using the phase variation of the Bragg facet reflectivity to improve the tunability. The modelling yields a 20 nm tuning range corresponding to a 8 nm increase of the classic DBR tunability. Preliminary experimental results confirmed this tuning imp...
