    摘要: A light emitting apparatus having a surface emitting laser (120) including a substrate (100), a first reflection layer (122), an active layer (123) and a second reflection layer (127) stacked successively on the substrate (100), first and second electrodes (110, 130) formed respectively on the lower surface of the substrate (100) and a portion of the upper surface of the second reflective layer (127), to emit light in the direction of the stacked layers, and a monitoring photodetector (150) stacked on the second reflection layer (127) so as to detect the amount of the emitted light from the surface emitting laser (120), is provided. The monitoring photodetector (150) includes first semiconductor material layer (151), an absorbing layer (157) and second semiconductor material layer (158) stacked successively on the second reflection layer, a third electrode formed on the second semiconductor layer to output detecting signals of the monitoring photodetector (150), and a controlling layer (152) formed on the bottom of the absorbing layer (157) and which intercepts some of the incident light.
