Low power electrochromic variable optical attenuator with 50dB attenuation range

A variable optical attenuator based upon a new molybdenum electrochromic compound is described. The device exhibits an attenuation range of >50dB at 1310nm, for a drive power of 150/spl mu/W, and an insertion loss of 1.5dB.
