Abstract:
1. A semiconductor light emitting device comprising: a first-conductivity-type first multilayer film reflecting mirror, and a second-conductivity-type second multilayer film reflecting mirror; a cavity layer arranged between the first multilayer film reflecting mirror and the second multilayer film reflecting mirror; and a first conductive section, a second conductive section, and a third conductive section used for current injection to the cavity layer, wherein the cavity layer has a stacked configuration including a first-conductivity-type or undoped first cladding layer, an undoped first active layer, a second-conductivity-type or undoped second cladding layer, a second-conductivity-type first contact layer, a first-conductivity-type second contact layer, a first-conductivity-type or undoped third cladding layer, an undoped second active layer, and a second-conductivity-type or undoped fourth cladding layer in this order from the first multilayer film reflecting mirror side, the first conductive section is electrically connected to the first multilayer film reflecting mirror, the second conductive section is electrically connected to the second multilayer film reflecting mirror, and the third conductive section is electrically connected to the first contact layer and the second contact layer, wherein the cavity layer has a column shape, and includes a first exposed face in which a part of an upper surface of the first contact layer is exposed from a side face of the cavity layer, and a second exposed face in which a part of an upper surface of the second contact layer is exposed from the side face of the cavity layer, wherein the third conductive section is formed over an upper surface of both of the first exposed face and the second exposed face, and wherein an etching stop layer is arranged between the second contact layer and the third cladding layer.
