Title: Exploring the Innovations of Philip Henry Wisseman
Introduction
Philip Henry Wisseman is a prominent inventor based in Hermosa Beach, California, known for his groundbreaking contributions to optical signal processing. With seven patents to his name, Wisseman has made significant strides in the field of optically channelizing radio frequency (RF) signals.
Latest Patents
One of his notable inventions is the "All Optical RF Signal Channelizer." This innovative device is designed to optically channelize RF signals that are modulated onto an optical carrier. It achieves this by optically separating the RF signals and mapping them using an optically dispersive element, such as a diffraction grating. The channelization process can be further enhanced through the use of two stages of optical filter elements in series, employing Bragg reflection gratings for coarse filtering into predetermined bands. Additionally, Fabry-Perot filters fine-tune the channelization into specific sub-bands of the Bragg reflection gratings. Alternate embodiments of this invention may include a silica planar waveguide and an optical splitting device, such as a Talbot splitter.
