    Surface emitting laser and optical coherence tomography apparatus including the same

    A surface emitting laser includes a lower reflector, an active layer, and an upper reflector that are arranged in that order; an air gap provided between the active layer and the upper reflector; and a slab provided on an optical path of the air gap and having a refractive index that is higher than a refractive index of the air gap. A position of at least one of the upper reflector and the lower reflector in an optical axis direction is changed to change a wavelength of emitted light. In the case where the position of the upper reflector is ...
