Surface input / output optoelectronic device |
| abstract |
(57) [Summary] [Objective] A surface emitting laser device having the same basic layer structure and a low laser oscillation threshold and a light receiving device having a wide light receiving band are formed on the same surface. [Structure] The DBRs 2, 4 and 11 constitute a resonator, and the active layer / absorption layer 8 inserted between the DBR 4 and the DBR 11 serves as a light emitting portion 17 and a light receiving portion 16, respectively. Further, the light receiving band is widened by inserting the spacer layer 3 having a half wavelength of the medium in the light receiving portion. [Effect] A low threshold value and a low resistance can be realized by simply changing the layer structure by using the technique of manufacturing the vertical cavity surface emitting semiconductor laser. |
