Title: Zhihong Mai: Innovator in Optical Fiber Technology
Introduction
Zhihong Mai is a prominent inventor based in Singapore, known for his significant contributions to optical fiber technology. With a total of 10 patents to his name, he has made remarkable advancements in the field, particularly in the design and manufacturing of optical devices.
Latest Patents
One of his latest patents is titled "Gamma groove arrays for interconnecting and mounting devices." This invention discloses devices with gamma (γ) grooves that can be utilized to form optical fiber arrays. The γ grooves are created using a dry etch process, such as Reactive Ion Etching (RIE), by modifying the resist features of an etch mask to have convex curved sidewalls. This innovative approach allows for the profile of the resist features to be transferred to the substrate, forming the γ grooves without the use of potassium-containing etchants, thus avoiding contamination and health issues associated with handling alkali-containing devices.
Another notable patent is "Wedge-shaped fiber array on a silicon-photonic device and method for producing the same." This patent describes a method for forming a wedge-shaped fiber array and a bottom base according to a probing pad layout of a silicon-photonic device. This design enables simultaneous optical, DC, and RF mixed signal tests, enhancing the functionality of silicon-photonic devices during wafer-level testing.
