Abstract :
A wavelength multichannel DBR laser exhibiting a -3 dB IM bandwidth up to 8 GHz has been demonstrated. By monitoring only one current in the DBR section, the highest number (18) ever reported of wavelength channels regular spaced has been obtained on a three section DBR structure which was optimised in terms of active-passive coupling efficiency and lengths.
