Abstract
This study extends the lateral metal grating technology to the fabrication of GaInAsSb/AlGaAsSb single mode DFB lasers in the 2.4 /spl mu/ range. Laser characterization and measurements have been performed at 20/spl deg/C and 40/spl deg/C in order to show the constant temperature sensitivity over the whole grating range. The wide gain spectrum of the GaSb structures permits the realization of DFB lasers from 2.339 up to 2.392 /spl mu/m by variation of the grating periods from 326.88 nm to 334.88 nm.
