Abstract :
A flat red-shifted FM response over a 1 GHz bandwidth has been achieved in a newly fabricated three-electrode DBR LD. Since the DBR structure makes it possible to tune the wavelength without distorting the FM characteristics, the LD is suitable for transmitters in optical FDM communications using FSK lightwaves.
