摘要
In accordance with the invention, a reconfigurable optical fiber grating comprises an optical fiber grating with a temperature sensitive material surrounding the cladding region or incorporated into the cladding region. One or more heating elements are arranged to produce a a temperature gradient along the length of the grating and thereby chirp the grating. In a preferred embodiment, a long period fiber grating is surrounded by a material in which dn/dT is 10 times as large as that of glass and in which n is close to but lower than that of the glass. A temperature gradient along the length of the grating results in a broadening of the resonance.
