N2 - An ultrawide, tunable band rejection filter was experimentally demonstrated operating from 1060 to 1670 nm seamlessly covering all communication bands (O, E, S, C, L, and U bands). The device consists of a micro-optical waveguide made from fused taper fiber coupler mounted over a microactuating platform that systematically applies a highly localized torsional stress over the coupling region. High-band rejection efficiency of 20-30 dB and very low insertion loss of 0:2 dB were experimentally achieved over the whole operating spectral range.
