Latest Patents

Lianxiang Yang holds a patent for a "Fast Attenuator." This invention provides a fast variable optical attenuator that includes a reflective membrane serving as a varifocal mirror. The electrostatic deflection of the mirror defocuses the optical system and attenuates an optical signal launched from an input port to an output port. The design achieves fast attenuation within a small dynamic range of less than 5 dB. The dynamic range is further improved by combining the fast attenuator with a slower attenuator, which are optically coupled via free space or integrated into the same device. This compact arrangement reduces excess loss associated with optical fiber coupling and lowers packaging costs.
