Abstract

The invention discloses a wide-temperature and high-stability temperature adaptive flattening compensation device, which comprises a bottom plate and at least two temperature drivers, wherein the bottom plate comprises a moving part I, a moving part II and a rotary connecting shaft; the side end of the moving part I is provided with a lug I and a lug II, the side end of the moving part II is provided with lug III, the lug I, the lug II and the lug III correspond to each other, the temperature drivers are respectively installed between the lug I and the lug III and between the lug II and the lug III, at least one of the temperature drivers is fixed at one end and movable at the other end, and at least one temperature driver is fixed at both ends; and the expansion coefficient of the bottomplate is different from the expansion coefficient of the temperature drivers. The device disclosed by the invention adopts two or more temperature drivers, and can move automatically according to changes of the environment, thereby compensating the temperature dependence of a PLC optical waveguide device, and enabling the temperature compensation curve to be more flattened. In addition, at least three rotating shafts are adopted to enhance the reliability and the stability.
