摘要
We present a method for metal coating optical fiber and in-fiber Bragg grating. The technology process which is based oil electroless plating and electroplating method is described in detail. fiber is firstly coated with a thin copper or nickel plate with electroless plating method. Thou, a thicker nickel plate is coated oil the surface of the conductive layer. Under the optimum conditions, the surfaces' of Chemical plating and electroplating coatings are all smooth and compact. There is no visible defect, found ill the cross-section. Using this two-step metallization method, the, in-fiber Bragg grating call be, well protected and its thermal sensitivity can be enhanced. After the metallization process, the fiber sensor is successfully embedded ill the 42CrMo steel by brazing method. Thus a smart metal structure is achieved. The embedding results show that the plating method for metallization protection of in-fiber Bragg grating is effective.
