Abstract :
New electronically controlled infrared variable optical attenuators based on thin film electrochromic technology are presented. Initial ECVOA prototypes have up to 15 dB attenuation range, 0.5 dB insertion loss, and a switching rate of 5 dB/sec. These devices are broadband, continuously variable, compact and polarization insensitive.
