Zusammenfassung: | To control the emission direction of laser beam with simpler structure.SOLUTION: A light emitting device is provided, comprising: a laser beam generating unit which resonates laser beam in a resonance region of a first surface and a second surface facing each other and emits the laser beam from the first surface; a substrate which is provided on the first surface of the laser beam generating unit and transmits the laser beam while absorbing a part of the emitted laser beam; and a plurality of control electrodes which are provided on the second surface of the laser beam generating unit and face each other, with the resonance region interposed between them.SELECTED DRAWING: Figure 1
【課題】より簡易な構造にてレーザ光の出射方向を制御する。【解決手段】互いに対向する第1面及び第2面の共振領域にてレーザ光を共振させ、前記第1面から前記レーザ光を出射するレーザ光生成部と、前記レーザ光生成部の前記第1面に設けられ、出射された前記レーザ光の一部を吸収しつつ、前記レーザ光を透過させる基板と、前記レーザ光生成部の前記第2面に設けられ、前記共振領域を挟んで対向する複数の制御電極と、を備える、光出射装置。【選択図】図1 |
