Title: Wenshen Wang: Innovator in Photonic RF Technologies
Introduction
Wenshen Wang is a notable inventor based in Torrance, California. He has made significant contributions to the field of photonic RF technologies, holding a total of 3 patents. His work focuses on innovative systems that enhance the generation and distribution of radio frequency signals.
Latest Patents
Wang's latest patents include a photonic RF distribution system. This system provides a method for distributing an RF output signal using two optical sources that generate optical signals. The first optical source generates a first optical signal with a specific operating frequency, while the second optical source generates a second optical signal with its own operating frequency. A modulator impresses an RF modulation signal on a portion of the first optical signal, creating a modulated signal. This modulated signal is then combined with a portion of the second optical signal to form a combined signal with a difference frequency component. A control photodetector generates a tone signal that helps maintain frequency locking between the two optical signals.
Another significant patent is for a slow wave optical waveguide designed for velocity-matched semiconductor modulators. This invention features a PIN electro-optical traveling wave modulator that includes diffraction gratings positioned on opposing sides of an optical waveguide. These gratings alter the propagation pattern of the waveguide, allowing the optical wave to interact with the RF wave in the transmission line effectively. The design includes various layers and electrodes that facilitate this interaction, ensuring optimal performance.
