It is proposed for the first time how an electrically poled chirped Bragg grating in an optical fiber may be used for creating efficient, electrically controllable optical fiber delay lines. The tunable range for the delay can be chosen by fixing the chirp rate of the Bragg grating. Additionally, strain and temperature may be used to change the centre wavelength of the delay line. Dispersion may also be used to increase phase-modulation in nonlinear optical fibers.
