Abstract
We demonstrate an all-fiber bandpass filter with 2-nm bandwidth and mo re than 25 dB of nonresonant light suppression (ignoring sidelobes) in a 60-nm-wide spectral range around its central wavelength, This novel device uses a pair of long-period gratings to couple resonant light f rom the fiber core into the cladding and then back into the core. The amplitude transmission through the filter is dynamically adjustable ov er a 20-dB range.
