Abstract

A novel micromachined electromagnetic actuated variable optical attenuator is described. The attenuation level is adjusted by changing the lateral distance between two V-groove-aligned single-mode fibers. Based on the waveguide transmission theory, the relationship between the attenuation and the offset is analyzed. The fabrication of the device only enrolls common and well-known semiconductor technologies. The packaged volume of the device is 20×10×5 mm³. According to the experiment results, the insertion loss is less than 1 dB, the polarization dependent loss is less than 0.1 dB, dynamic range is larger than 50 dB, and the driving voltage is less than 5 V. It is proven to be a low-cost, high-performance passive device for future all-optical networks.
