Title: The Innovative Contributions of Charles Wong
Introduction
Charles Wong is a prominent inventor based in Richardson, TX, known for his significant contributions to optical technologies. With a total of 10 patents to his name, Wong has made remarkable advancements in the field of wavelength division multiplexing and optical filtering.
Latest Patents
One of Wong's latest patents is a compact wavelength filter that utilizes optical birefringence and reflective elements. This innovative device is designed to separate odd and even wavelengths or upper and lower channels of an input optical signal. The filter first converts the input signal to a predetermined polarization, employing a series of birefringent waveplates to achieve a polarization-dependent optical transmission function. This results in the decomposition of the polarized beam into two components, each carrying different spectral bands. The device further includes a beam displacer that spatially separates these components into orthogonally-polarized beams, which are then converted into circularly-polarized beams for reflection and further processing.
Another notable patent is the programmable optical add/drop multiplexer, which provides an optical wavelength division multiplex (WDM) demultiplexer in a substantially passive form. This invention allows for the separation of alternate channels, resulting in outputs that contain even-numbered and odd-numbered channels, each with a bandwidth that is double the original channel separation bandwidth.
Career Highlights
Throughout his career, Charles Wong has worked with several notable companies, including Chorum Technologies Inc. and Macrovision Communications, Inc.
