Abstract
The spectral characteristics of a widely tunable super structure grati ng distributed Bragg reflector (SSG-DBR) laser are investigated and th e design considerations of the grating reflectors are given. By system atically adjusting the control currents of the two reflector sections and the phase section it is experimentally shown that every wavelength in an interval of 40 nm can be reached with a side-mode suppression u sually better than 30 dB.
