MEMS based Variable Optical Attenuators are gaining momentum and market share over competing traditional technologies in optical networks applications ranging from optical modules protection to the growing segment of Optical Power Management.

MEMSCAP has developed two families of Variable Optical Attenuators based on two different actuation principles:

• The MATT VOA family, based on thermal actuation, and existing in both normally open and normally closed configurations, and
• The ES VOA family, based on electro-static actuation, and existing in both high voltage and low voltage drive configurations.
