Abstract

A new method for increasing the modulation bandwidth of InGaAsP lasers is described herein. The method of the present invention is based on the gain enhancement doping of the lasers active layer. Lasers with highly doped active regions were demonstrated to have larger modulation bandwidths than lightly doped devices.
