Latest Patents

One of his latest patents is titled "Bidirectional multi-channel optical ring network using WDM techniques." This invention provides a bidirectional multi-channel all-optical ring network comprising several nodes linked by optical cables. Each node includes two WDM/WDDM packet switching devices and a node controller. In this network, a first optical signal group of wavelength channel signals is transferred in a counter-clockwise direction, while a second optical signal group is transferred in a clockwise direction. This design allows for the transmission of optical data signals through shorter distances.

Another significant patent is the "Fiber-optic address detector in photonic packet switching device." This invention features fiber-optic delay lines with a metal thin film evaporated on one surface. The fiber-optic delay lines are connected in a melting state to fiber-optic couplers. The inputting address photonic signals are tapped by the inputting fiber-optic couplers, reflected by the metal thin films, and then re-combined. This innovation reduces the number of fiber-optic couplers used in conventional detectors by half while maintaining the same address detection effect.
