基于光热效应的光强探测器及系统
摘要：
本发明涉及一种基于光热效应的光强探测器及系统，具体而言，涉及光强度测量领域。本申请通过将第一电极和第二电极分别设置在石墨烯层的一个面上，并处于石墨烯层的两端，并且给该第一电极和第二电极通电，当待测光纤中的光从该光强探测器的一端流向另外一端的时候，待测光纤中的光与该石墨烯层发生耦合，该石墨烯层的温度就会有所升高，根据该石墨烯层温度升高的情况就可以得到该石墨烯层的热噪声，根据该热噪声与该光强的对应关系，便可以直接得到该待测光纤中流过的光的光强。
摘要（英）：

The invention relates to a light intensity detector and a system based on a photothermal effect, and particularly relates to the field of light intensity measurement. A first electrode and a second electrode are respectively arranged on one surface of a graphene layer, and are located at two ends of the graphene layer, and the first electrode and the second electrode are energized; when flowing from one end of the light intensity detector to the other end, light in an optical fiber under test is coupled with the graphene layer, and the temperature of the graphene layer can increase to some extent; according to the temperature increase situation of the graphene layer, thermal noise of the graphene layer can be obtained; and according to a corresponding relationship between the thermal noiseand light intensity, the light intensity of the light flowing in the optical fiber under test can be directly obtained.
