Latest Patents

One of his latest patents is a polarization converter based on taking a high-order TE mode as a transition mode. This invention comprises a ridge waveguide and a slab waveguide arranged in double layers and varying in width, along with a strip waveguide that also varies in width. The ridge waveguide is positioned on the upper end face of the slab waveguide and is aligned with both ends of the slab waveguide. The right end of the ridge waveguide and the slab waveguide are connected to the strip waveguide, allowing for the conversion of TM mode into TE mode for output and vice versa.

Another notable patent is a silicon-germanium photoelectric detection apparatus based on an on-chip mode converter. This apparatus includes an insulating substrate, an optical coupler, an on-chip mode converter, and a multi-mode silicon-germanium photoelectric detector. The optical coupler, converter, and photoelectric detector are sequentially connected and fixed on silicon wafers of the insulating substrate. An incident fundamental mode optical signal is transmitted to the optical coupler through a single-mode fiber, where it enters the converter and is transformed into a multi-mode optical field. This field is then converted into an electrical signal by the photoelectric detector, enhancing the responsiveness of the apparatus.
