Automatic frequency control light amplifier
专利汇可以提供Automatic frequency control light amplifier专利检索，专利查询，专利分析的服务。并且PURPOSE:To realize a linear amplifier, in which Fabry-P erot resonance mode frequency automatically follows incident signal optical frequency, and an injection synchronous amplifier, in which oscillation frequency automatically follows incident signal optical frequency, by automatically tuning the oscillation frequency and resonance mode frequency of the light amplifier to incident signal optical frequency. CONSTITUTION:A light amplifier has a half mirror 4 for branching incident signal beams, a half mirror 5 for branching output signal beams, the light amplifier 6, a wave plate 7 giving the phase shift of pi/2, the wave synthesizer 8 of two optical signals and a photodetector 9. One part of the incident signal beams and one part of output signal beams are extracted by means of the half mirrors, the phase of the output signal beams is advanced only by pi/2, and two optical signals are synthesized. When currents injected are increased, carrier density increases and the resonance mode frequency is shifted to the high frequency side in the linear amplifier operating at oscillation threshold or lower, and the temperature of an active layer elevates and the oscillation frequency is shifted to the low frequecy side in the injection synchronous amplifier operating at oscillation threshold value or higher. N-P-N junction sections 10, 11, 12, 13 from a photo transistor, error optical signals are detected by the P-N junction of 12-13, and photocurrents amplified flow through the active layer 11.，下面是Automatic frequency control light amplifier专利的具体信息内容。
