Direct modulation characteristics of GaInAsP/InP d.h. lasers with various stripe widths measured by sharp-pulse method

Abstract
The direct modulation characteristics of GaInAsP/InP d.h. lasers emitting at 1.3 μm with various stripe widths were measured by the proposed sharp-pulse method. As a result, a flat modulation frequency response up to 1.9 GHz was observed in a laser diode with 5 μm stripe width.
