Abstract

A different type of thermally tuned chirped Bragg grating is presented. The device consists of an unchirped intracore grating in a bare fiber that is coated with a thin film of metal whose thickness varies along the length of the grating. Electrical current passing through the film generates local resistive heating at rates that, neglecting the temperature dependence of the resistivity, are inversely proportional to the thickness of the film when this thickness is relatively small compared to the diameter of the fiber.
