✦ Synopsis

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 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 s
