Abstract (in Japanese) (See Japanese page) 
(in English) A quantum structure intermixing (QSI) technique that suppresses the carrier diffusion and surface recombination current was applied to vertical cavity surface emitting lasers (VCSELs) for decrease of the device size and power consumption, and increase of the efficiency. The QSI process of applying the thermal annealing after SiO2 deposition has been examined in quantum well samples. VCSELs were fabricated by using the QSI process from lateral direction at the mesa side wall. A 15 m square mesa VCSEL showed 70% decrease of the threshold current and 70% increase of the quantum efficiency in comparison with a non-QSI VCSEL. We also discuss another mechanism of improved characteristics besides the QSI technique.
