摘要The spectrum shape of conventional fiber Bragg gratings is near-rectangular. By means of a discrete layer peeling method we numerically study fiber Bragg gratings with right-angled triangular spectrum. Fiber Bragg grating structures with single- and multi-channel right-angled triangular spectra are synthesized. These kinds of devices provide potential applications in wavelength interrogation in optical sensor systems.
