Electrooptical Devices
Abstract
The small-signal frequency response of small-contact mass-transported buried-heterostructure lasers with minimal parasitic contact pad capacitance has been measured. Initial results show that the highest relaxation frequency of 5 GHz is obtained in long lasers with high optical power. GaInAsP/InP buried- heterostructure lasers fabricated on p-InP substrates offer considerable advantages in terms of reduced series resistance because of the large-area p- contact. A simple formula has been derived from permits an accurate calculation of the spreading resistance in the p-InP. Keywords: Gallium arsenides, Indium phosphides.
