INTRODUCTION:
MEMS VOA is a precise and adjustable voltage-driven optical component. The key part of the
component is MEMS chip; driving voltage produces electrostatic force to drive the micro-mirror
on the chip, then to adjust output optical power. It has excellent features such as compact
dimension, low power consumption, fast responding, anti-shock, low WDL as well as low PDL. It
is successfully applied in military project. It meets reliability standard of Telcordia 1221.MEMS
VOA has 2 series: fast responding series and low voltage driving (LOWO) series. Each series
has variable models like single wavelength, dual wavelength, and polarization-maintaining.
We could also develop and produce other MEMS VOA as customers' requirement.
