Abstract
Sampled Bragg gratings consist of a periodic modulation of the amplitude and/or the phase of the Bragg grating. In the frequency domain, their reflectivity spectrum shows a number of equally spaced peaks, covering a range of wavelengths determined by the Fourier contents of the modulation, or "sampling" function. Sampled gratings have been used in DBR semiconductor lasers to extend their tuning range [1].
