We have recently reported short-cavity In/sub 0.35/Ga/sub 0.65/As/GaAs MQW lasers with modulation bandwidths up to 33 GHz using beryllium (Be) as p-dopant in the active region. At the growth temperatures used for this structure, however, a modulation-type p-doping in the core can not be realized due to the redistribution of Be during the growth process. In this work, we present InGaAs/GaAs MQW lasers with a similar epilayer structure, but with the Be-doping in the core replaced by carbon (C), resulting in a modulation-doped core region. Short-cavity lasers fabricated using this epilayer structure demonstrate record CW direct modulation bandwidths up to 37 GHz in 6x130 /spl mu/m/sup 2/ devices at room temperature.
