Abstract
GalnAsP/InP vertical cavity surface emitting laser diodes (SELDs)1-4 are attracting much interest for new era optical fiber communication systems and optical interconnects. Although good performance has been shown by optical pumping,5,6 the threshold current of injection devices at room temperature was still higher than that of edge emitting lasers, and the highest cw lasing temperature was — 138°C.4 In this study, we have drastically improved the performance of 1.3 µm GalnAsP/InP SELD.
