Introduction: C Jacob Sun is an accomplished inventor based in Saratoga, CA (US). He has made significant contributions to the field of optical devices, particularly through his innovative patent related to low loss optical waveguide devices. His work has implications for various applications in optical technology.

Latest Patents: C Jacob Sun holds a patent for a low loss optical waveguide device. This patent describes a method for forming optical devices on planar substrates. The method utilizes a linear injection APCVD process to create optical waveguide devices at approximately atmospheric pressure. The process involves placing a wafer with a lower cladding layer on a conveyer, which may include a heating element. The heated wafer is then transported beneath a linear injector, allowing chemicals to react on the wafer surface and form a core layer. Following the formation of the core layer, photoresist is applied, and standard lithography is used to pattern the optical devices. Reactive ion etching (RIE) is then employed to create waveguide lines, and the remaining photoresist is removed. Finally, an upper cladding layer is formed to cover the core regions, ensuring that the refractive index of the core layer is generally 0.2% to 2% greater than that of the upper and lower cladding layers.
