Abstract
We report what we believe is the first example of efficient rocking filter formation in polarization-maintaining photonic crystal fiber. Very high coupling efficiencies (as much as suppression of the input polarization) and loss of were achieved for fibers as short as 11 mm. The filters, which we prepared by periodic mechanical twisting and heating with a scanned laser beam, are highly compact, and they are expected to be temperature stable.
