| Zusammenfassung: | A vertical cavity surface emitting device includes a substrate, a first multilayer film reflecting mirror formed on the substrate, a light-emitting structure layer formed on the first multilayer film reflecting mirror and including a light-emitting layer, and a second multilayer film reflecting mirror formed on the light-emitting structure layer. A resonator is constituted between the second multilayer film reflecting mirror and the first multilayer film reflecting mirror. The light-emitting structure layer includes a low resistance region and a high resistance region. The low resistance region is disposed in a ring shape between the first multilayer film reflecting mirror and the second multilayer film reflecting mirror. The high resistance region is formed inside the low resistance region and has an electrical resistance higher than an electrical resistance of the low resistance region. |
