    摘要: A VCSEL includes a first conductivity-type first semiconductor mirror layer on a substrate, an active region thereon, a second conductivity-type second semiconductor mirror layer thereon, and a current confining layer in proximity to the active region. A mesa structure is formed such that at least a side surface of the current confining layer is exposed. The current confining layer includes a first semiconductor layer having an Al-composition and a second semiconductor layer having an Al-composition and being formed nearer to the active region than the first semiconductor layer does. Al concentration of the first semiconductor layer is higher than that of the second semiconductor layer. When oscillation wavelength of laser light is λ, optical thickness being sum of the thickness of the first and second semiconductor layers is λ/4. The first and second semiconductor layers are selectively oxidized from the side surface of the mesa structure.

    摘要: A VCSEL includes a first distributed Bragg reflector (DBR) of a first conductivity type formed on a substrate and including at least one semiconductor layer to be oxidized, an active region having a column shaped structure and formed on the first DBR, and a second DBR of a second conductivity type. At least one hole starting from a surface of the first DBR and reaching the at least one semiconductor layer to be oxidized is formed in the first DBR outside of a column shaped structure of the second DBR. An oxidized region is formed in the semiconductor layer to be oxidized by selectively oxidizing from a side surface of the hole. In the first DBR, a first current path is formed by a conductive region surrounded by the oxidized region, and a second current path is formed by a conductive region not surrounded by the oxidized region.
