Abstract
Operation of a LOC‐DBR laser which exhibits high differential quantum efficiency is reported. It is shown that this result is obtained by further reduction of losses in the unpumped regions of the laser, especially, excessive absorption losses due to nonuniform Al carryover in the thin ’’GaAs’’ layer.Keywords
