Paper Abstract

A novel variable optical attenuator (VOA) based on fiber Sagnac interferometer is proposed and demonstrated. This VOA is constructed with a 3dB coupler and a polarization controller. By tuning the polarization controller, the output power can be adjusted easily. With the advantage of all fiber design, simple structure and essentially polarization independent, The VOA has an attenuation range more than 20dB, a wavelength ripple of 0.07 and its insertion loss is lees than 0.7dB.
