专利汇可以提供Light amplitude modulator专利检索,专利查询,专利分析的服务。并且PURPOSE:To perform amplitude modulation with small insertion loss and high quenching ratio by separating incident light to mutually orthogonal polarization components to modulate the same and combining only the light to be modulated. CONSTITUTION:Incident light 21 polarized in the X axis direction enters the lithium tantalate crystal 22 which is so formed as to transmits light in the Y axis direction and when a voltage is applied to the interdigital electrode 23 provided thereon, the incident light is converted to the exit light 24 having been polarized in the Z axis direction. On the other hand, the incident light 25 polarized in the Z axis direction is made to the exit light 26 polarized in the X axis direction through voltage application. The use of such modulator enables amplitude modulation to be performed with low power and less insertion loss and high quenching ratio.,下面是Light amplitude modulator专利的具体信息内容。
