Abstract
We designed and experimentally studied a sampled Bragg grating semiconductor laser with π equivalent phase shift (EPS) and three equally separated electrodes. When the central electrode is injected different current from the other electrodes, a distributed phase shift (DPS) can be introduced into the studied laser. By changing the injection current ratio into three electrodes, the DPS can be controlled and then the lasing wavelength can be tuned while the laser keeps single longitudinal mode operation.
