Abstract

PURPOSE:To obtain an emitted light whose light intensity is larger than that of incident one and has a high directivity, by integrating a photoelectric conversion part and a surface emitting type semiconductor laser oppositely on a semiconductor substrate. CONSTITUTION:In an optical amplifier for amplifying an incident light or converting a wavelength to output a light, a photoelectric converter 103 for converting an incident light 115 into an electric signal and a surface emitting type semiconductor laser 102 for converting an electric signal into a laser light are provided, and the converter 103 and the laser 102 face to be integrated on a semiconductor substrate. That is, since the laser light is internally amplified, the light intensity is strong even with a low current different from a natural radiating light of an LED, and the light is radiated in a resonator direction. Accordingly, its directivity is high as a coherence light to be easily condensed. Thus, even if a signal current from a phototransistor is less, the light intensity of the radiated light can be sufficiently strengthened, the directivity of the light can be enhanced, and even if the lights are two-dimensionally arrayed, an optical amplifier which can raise its integration can be obtained.
