| 英文摘要 | PURPOSE:To contrive control of noise and to stabilize the gain of light amplification by absorbing the undesired light properly by using a reflection preventing film for light-input combination of the light amplifier and using a diffraction grating for light-output combination. CONSTITUTION:Between the positive electrode 408 and the negative electrode 409, a bias current flows in a normal direction. At this time, if the signal light 450 having an equal wavelength to the band gap of the active layer 402 is projected, the signal light 450 is amplified by the induced emission effect during wave-guiding of the active layer 402 in a light-amplifying region 420. The amplified light is then transmitted to a connection waveguide path region 430 and the light-amplifying region 420 and the connection waveguide path region 430 are combined without reflection. As the modulation period diffraction grating 405 having the period strucure in which the period becomes slightly shorter from the entering side toward the emitting side is arranged on a boundary plane between the layers 404 and 406 as a light frequency filter, the signal light makes a focus in the outside and is taken out as the output light 460. |
