Abstract
We present a novel method to fabricate fiber filters based on mechanically induced long‐period fiber gratings. Transmission spectra can be tailored by external pressures or by introducing a phase‐shift. As an example, the filter was used to flatten the spectral output from an Er‐doped superfluorescent fiber source. © 2004 Wiley Periodicals, Inc.

## A simple and efficient variable optical attenuator (VOA) is achieved by using microbend gratings on single-mode fiber (SMF). The flatness of the attenuator is maintained for 100 nm along the CϩL band spectrum. Controlling the pressure will vary the attenuation depth of the device.
## Abstract In this article, we present detailed results on the fabrication and characterization of mechanically induced gratings produced by winding a string around a fiber/tube set. A comparison between the mechanical and arc‐induced gratings is made, which allowed us to draw some conclusions on
