## Abstract We present a novel method to fabricate fiber filters based on mechanically induced longβperiod fiber gratings. Transmission spectra can be tailored by external pressures or by introducing a phaseβshift. As an example, the filter was used to flatten the spectral output from an Erβdoped s
