MEMS attenuators (MEMS VOAs) are based on a micro-electro-mechanical system (MEMS) technology. It is a micro-optic component designed for next generation, dynamically configurable optical networks. It is based on the Photonic Integrated Circuit (PIC) and electrostatic MEMS technology. The reflective mirror MEMS technology enables the creation of products with high attenuation levels and can be configured as bright or dark devices. When combined with the advanced packaging and manufacturing capabilities, this results in a new category of MEMS components that are designed to exceed specifications for performance, compactness, manufacturability and reliability. we provide a series of customized MEMS VOA products to meet different requirements on operating wavelength, attenuation type, drive voltage and fiber type.

Attenuation curve
MEMS VOA temperature attenuation curve: the abscissa is the voltage (V), and the vertical index is the attenuation value of the VOA (dB).
In the figure, the attenuation curves of VOA at -40°, -20°, 0°, 25°, 70°, and 85° are represented by different colors, respectively.
