    摘要: This invention discloses a plurality of compensating devices for correcting temperature deviation of optical fiber Bragg grating (FBG). These devices includes means for compressing optical fibers being affixed to a substrate, and fiber grids being cured to the substrate and/or the compressing means under a thermal state, or fiber grids being affixed to the substrate and/or the compressing means while the fiber grids are under tension. This invention further discloses methods for manufacturing such devices. The FBG thermal compensating devices according to this invention consist the advantages of simple constructions and simplified manufacturing processes. One of the devices can resolve the heat-dissipating problem so as to allow immediate thermal expansion of the fiber grids. Another device allows rapid positioning and manufacturing. One of the devices allows the fiber grids to be directly secured to a thermal compensating substrate without needing additional pre-processes. During the manufacturing processes, AB thermally cured adhesive can be implemented to affix the fiber grids to the device under a thermal state so as to eliminate the implementation of pre-loading. The device can also be placed under a thermal state, after the process of thermal curing, for a pre-determined period of time so as to perform annealing to the fiber grids thereby further simplifying the manufacturing process.

    摘要: The present invention discloses a process for the preparation of zirconium tungstate (ZrW2O8) ceramic body, comprising a reactive sintering step to react and sinter powders of the raw materials comprising a Zr-containing compound and a W-containing compound to form a zirconium tungstate ceramic body. The addition of zirconium tungstate powders as the seeds in the process can effectively reduce the steps, shorten the preparation time, lower the sintering temperature and duration, save the cost, and provide the zirconium tungstate ceramic body with uniform microstructure. Also, a process for the preparation of modified zirconium tungstate ceramic body is disclosed, by forming a second phase in the zirconium tungstate ceramic body to tune the thermal expansion coefficient of the zirconium tungstate ceramic body. The present invention also relates to the use of the modified zirconium tungstate ceramic body to provide a temperature compensated fiber bragg grating (FBG) device.
