“…Since the Bragg wavelength of an FBG is sensitive to applied strain, chirp rate tuning can be achieved by applying a strain gradient along the length of the grating with a flexible beam. Several techniques based on the beam-bending method have been proposed [1][2][3][4][5][6]. However, all these methods show drawbacks such as small tuning range (typically less than 6 nm in bandwidth), relatively large nonlinear chirp caused by non-pure bending and difficulty in operation and precise control.…”

An efficient scheme to change the chirp rate of a fiber Bragg grating (FBG) has been developed based on a specially-designed cantilever beam with the beam-bending method. It allows, to date, the largest tuning range of 36 nm in reflection bandwidth of a chirped-FBG (CFBG) while keeping the center wavelength nearly fixed during the tuning process. Using this method, bandwidth-tunable fiber grating filters with tunable chromatic dispersion or differential group delay have been demonstrated. Channel spacing-tunable multi-wavelength filters based on both sampled-and superimposed-CFBGs have also been realized. Moreover, tuning of the bandwidth and channel spacing is continuous with this scheme that makes the achieved devices more flexible.

“…Out of the several different techniques that have been proposed in the literature, the ones which seem to hold immediate promise could be classified as dispersion compensating fibers (DCF) [7], chirped fiber Bragg gratings (FBG) [8,9], high-order mode (HOM) fibers [10], virtual-imaged phased-array-based microoptic device [11]. In a chirped grating the optical pitch (product between the grating period and the mode effective index) varies along length of the FBG.…”

“…Tunable chirp rate FBG has devisable bandwidth, and dispersion compensates characteristics. Therefore, chirped tuning FBG has many applications, such as adjustable reflection bandwidth filter, tunable dispersion compensator, and optical fiber sensors [1–3]. Numerous FBG chirped tuning methods are demonstrated.…”

In this article, fiber Bragg grating chirped tuning method is theoretically and experimentally demonstrated. Using a double‐arched structure and a metal diaphragm, a vertical pressure can be transmitted to grating. According to different metal diaphragm shapes and grating pasted paths, by changing the pressure, fiber grating spectrum chirped tuning can be achieved. When it is pressurized, the internal strain distributions of metal diaphragm are simulated using finite element method. This uniform fiber Bragg grating chirped tuning method is also experimentally studied. The chirped tuning of fiber Bragg grating can be achieved. By introducing a correction factor, the theoretical and experimental results agree very well. © 2012 Wiley Periodicals, Inc.
