Integrated all-fiber variable optical attenuator based on index-guiding holey fiber

Paper Abstract

We report an integrated all-fiber variable optical attenuator (VOA) for dynamic control of a device by achieving optimized taper and axial compression of an index-guiding holey fiber. We experimentally demonstrate a VOA device with dynamic ranges of 18 dB over the spectral range from 1450 to 1650 nm and a low insertion loss of 0.5 dB.
