With a total of 2 patents, his work focuses on innovative fabrication methods that enhance the performance and efficiency of VCSEL technology.

Latest Patents

One of his latest patents is titled "VCSEL and the fabrication method of the same." This invention describes a fabrication method that forms a contact electrode on a VCSEL within a resonance cavity. A heavily doped layer is strategically placed in the resonance cavity where the light intensity is weakest. The method involves etching a Bragg reflector while ensuring the etching stop point is above the heavily doped layer. This process allows for the creation of a high-carrier-concentration ohmic channel, connecting the electrode to the heavily doped layer without requiring high etching precision.

Another notable patent is "Resonant cavity device array for WDM application and the fabrication method of the same." This specification outlines a resonant cavity device array designed for wavelength division multiplexing (WDM). The structure of the resonant cavity device is selectively formed with an oxide structure that includes multiple AlGaAs oxide tuning layers. The oxidation of AlGaAs results in the formation of AlGaO, which alters the refractive index and thickness, thereby controlling the wavelength of the resonant cavity device. The wavelength variant of each device is determined by the number of layers, thicknesses, and compositions of the AlGaAs oxide tuning layer.
