RESUMO
A method of fabricating a tilted fiber Bragg grating (TFBG) with a designed reflection spectrum profile is proposed and demonstrated experimentally. In a reflective TFBG the central wavelength and the reflectivity are dependent on the tilt angles. Controlling the rate at which the tilt angle is continuously varied and the exposure dose in the UV-light writing process permits accurate control of the bandwidth and reflectivity of the grating. The experimental result agrees well with TFBG theory and calculation.
