With a total of three patents to his name, Wang's work has advanced the technology used in various applications.

Latest Patents

Wang's latest patents include a vertical cavity surface emitting device with a buried index guiding current confinement layer. This innovative device features a buried index-guiding current confinement aperture layer that is lithographically processed to define the position, shape, and dimension of an inner aperture. The regrowth process fills the aperture with a single crystalline material, enhancing both current and optical confinement, which leads to higher optical power output and improved thermal conductivity.

Another notable patent is for oxide spacer HCG VCSELs and fabrication methods. This patent describes a high-contrast grating (HCG) structure and its method of fabrication. The HCG grating is formed over a structural spacer layer, allowing for a wider range of grating patterns. The technique involves etching the HCG grating and oxidizing through it into an oxide spacer layer beneath, creating a low-index area that can be utilized as reflectors in fabricating VCSELs.
