Abstract

We report the improved LPE regrowth prooess o InGaAsP/InP BR lasers.This method is based on the efeot o laP layers growth seleotivity. The proposed etched mesa proi1e provides the localization o! blocking p-n-junction on the mesa sidewall in the close vicinity o active layer. The mechanism responsible ror the increase of threshold current density(Jth) and the decrease o differential quantum eicienoy (ηd) in narrow (W<1Oμm) BR lasers was revealed in the set or special experiments. The modification of the rerowth process allowed to improve the lasing characteristics and to achieve 160 mW single-lobe output.
