Abstract
We report the characteristics of Be-modulation-doped strained multiple -quantum-well (MQW) buried heterostructure lasers grown by chemical-be am epitaxy. Secondary ion mass spectroscopy revealed that the Be-modul ation-doping profile was fabricated and maintained even after annealin g at 620-degrees-C for 30 min, which is the same condition used to fab ricate the buried heterostructure. A linewidth enhancement factor (alp ha parameter) of only 0.8 was obtained in 3X10(18) cm-3 Be-modulation- doped strained MQW Fabry-Perot lasers at a wavelength of 35 nm shorter than the gain peak.
