Title: Innovations of James K Eu
Introduction
James K Eu is an accomplished inventor based in Fremont, CA, known for his contributions to optical devices. He holds a total of 2 patents, showcasing his expertise in the field of photonics and optical engineering.
Latest Patents
His latest patents include a "Low loss optical waveguide device" and a "Fiber optics signal attenuator." The low loss optical waveguide device patent describes a method for forming optical devices on planar substrates using a linear injection APCVD process. This method operates at approximately atmospheric pressure and involves placing a wafer with a lower cladding layer on a conveyer. The heated wafer is then transported beneath a linear injector, allowing chemicals to react on the wafer surface to form a core layer. Following this, photoresist is applied, and standard lithography is used to pattern the optical devices. Reactive ion etching is then employed to create waveguide lines, and an upper cladding layer is formed to cover the core regions. The refractive index of the core layer is designed to be greater than that of the cladding layers, ensuring optimal performance.
The fiber optics signal attenuator patent describes an innovative device for use in a wavelength division multiplexer (WDM). This attenuator utilizes an opaque knife-edge that can be moved along a single axis to controllably block the light output of an optical fiber. By adjusting the position of the knife-edge, the device can selectively block varying amounts of light output, making it a versatile tool in optical communications.
