Surface emitting laser, and transceiver, optical transceiver, and optical communication system employing the surface emitting laser |
摘要 |
A surface emitting laser includes a lower semiconductor multilayer mirror formed of a plurality of pairs of a high-refractive-index area and a low-refractive-index area; an active layer vertically sandwiched by cladding layers; a current confinement layer of AlzGa1-zAs having an oxide area in a peripheral portion of the current confinement layer, where 0.95<=z<=1; and an upper semiconductor multilayer mirror formed of a plurality of pairs of a high-refractive-index area and a low-refractive-index area. The low-refractive-index area of at least one of the lower semiconductor multilayer mirror and the upper semiconductor multilayer mirror includes an Alz1Ga1-z1As layer with a thickness thinner than that of the current confinement layer, where z<=z1.
