Abstract: The present disclosure provides a MEMS-based variable optical attenuator (VOA) array, sequentially including an optical fiber array, a micro-lens array, and a MEMS-based micro-reflector array to form a VOA array having several optical attenuation units. The MEMS-based micro-reflectors can change the propagation direction of a beam, causing a misalignment coupling loss to the beam and thereby achieving optical attenuation, with a broad range of dynamic attenuation, low polarization dependent loss and wavelength dependent loss, good repeatability, short response time (at the millisecond level), etc. Arrayed device elements are used as assembly units of the present disclosure, and the assembly of arrayed elements facilitates tuning in batches. Accordingly, automation levels are improved, and the production costs are reduced.
