Abstract:
A surface emitting laser is formed of a composition in which bandgap energy of layers from immediately above a current confinement layer to a second conductivity type contact layer is reduced towards the second conductivity type contact layer in a stacking direction, and a composition in which bandgap energy of layers from immediately below the current confinement layer to a first conductivity type contact layer is reduced towards the first conductivity type contact layer in a stacking direction while bypassing a quantum well layer or a quantum dot of an active layer, and includes a second conductivity type cladding layer including a material for reducing the mobility of carriers.
