Paper Abstract

In this paper, a new kind ofhigh precision mechanical variable optical attenuator (VOA) based on optical blocking slice is designed, fabricated and tested. The attenuation range is more than 40dB. The measured insertion loss and return loss are less than 0.5 dB and larger than 65dB respectively. The best resolution is 0.001dB. The attenuator has high attenuating precision, low insertion loss, high return loss, polarization independent, wide temperature range, wide spectrum scope, wide attenuation range, low cost and so on.
