Latest Patents

Zhifang Fang's latest patents include innovative designs for an optical fiber connector, a single-fiber bidirectional optical assembly, and an optical fiber transmission system. The optical fiber connector is specifically designed for use in a single-fiber bidirectional optical assembly that comprises a first optical module and a light filter. This connector features an optical path changing module, an optical fiber, a ferrule, and a tube. The optical fiber is housed within the ferrule, while the optical path changing module is in physical contact with the ferrule. The two components are secured together through the tube, with an optical path port located on the tube opposite the first optical module. This design allows the optical path changing module to effectively alter the transmission path of a first optical signal.

Additionally, Fang has developed an encoding apparatus that utilizes the same polarization modes, along with a quantum key distribution device and system based on this technology. This invention includes a polarization splitter-rotator (PSR), a polarization rotation structure, and a modulator. The PSR is responsible for receiving input signal light, splitting it into two parts with identical polarization modes, and directing them to the polarization rotation structure and the modulator. The polarization rotation structure can rotate the polarization direction of an optical signal by 180 degrees while maintaining the polarization direction of another signal unchanged. The modulator is designed to modulate the light input, and the PSR combines the output signals from both the polarization rotation structure and the modulator.
