Abstract

An adjustable long-period optical fiber raster structure and it manufacturing method are provided. Through temperature adjusting, the thermal expansion modulus mismatch among different materials makes optical fibers generate expected micro bending to form a mode coupling phenomenon similar with traditional optical grating. Furthermore, meet the function of modulating filter frequency spectrum by temperature control. Not only apply for optical communication and wavelength division multiplexing device equipments but also apply for detection of temperature and distortion. The invented adjustable long-period optical fiber grating structure consists of a substrate on which there is a periodic structure with first thermal expansion modulus, and a joint gel that is used to fix a optical fiber on the periodic structure and has a second thermal expansion modulus. The first thermal expansion modulus is different from the second's. Under temperature variation, the thermal expansion modulus difference of two materials, substrate and joint gel, results in micro bending of optical fiber to form a optical grating effect.
