19 August 1998Single-lobe operation of BA InGaAsP/GaAs SCH SQW lasers
It was observed that a twin-lobe like farfield appeared more obviously with larger stripe width of BA LD, also with increasing injected current, due to much more complicated lateral modes. As a consequence, a single-lobed farfield output of 2.0 W has been realized with BA InGaAsP/GaAs SCH SQW lasers (stripe width 150 um).
