WebAs a consequence of the interference laws, the interference filter will pass the most light at integer multiples of λ/2 and will pass the least amount of light at odd integer multiples of … WebA fiber Bragg grating is most efficient as a WDM signal filter when it reflects a single wavelength and transmits the other wavelengths. In this regard, a fiber Bragg grating resembles a thin-film coating, but there are significant differences. In a thin-film filter, the changes in refractive index are discontinuous and on the order of 10 —1 .
