Latest Patents

One of her latest patents is titled "High-power large-aperture fundamental mode vortex optical waveguide coherent VCSEL array." This invention provides a large-aperture array light-emitting structure that includes an N electrode layer, an N-type DBR, an active region, a P-type DBR, and a P electrode layer. The design features micro/nanostructures with hexagonal lattice arrangements etched on the surface of the light output aperture of each light-emitting unit mesa. These structures are filled with highly doped semiconductor transparent materials to create a vortex optical waveguide structure. This innovation combines the vortex optical waveguide structure with the traditional VCSEL array laser, enabling transverse and longitudinal regulation of the optical waveguide, current injection, and heat conduction, ultimately achieving a high-power and high-coherence fundamental mode VCSEL array.

Another notable patent is the "Method for transferring compound semiconductor single crystal thin film layer and method for preparing single crystal GaAs-OI composite wafer." This method involves preparing a graphite transition layer on a first substrate, growing a compound semiconductor single crystal thin film layer on this layer, and then preparing dielectric layers on both the first and second substrates. The process allows for the transfer of the thin film layer to the second substrate through a lateral external pressure application.
