Tech ID: 31655 / UC Case 2018-047-0

Abstract

Researchers at the University of California, Davis have developed a method for ultra-wideband and highly precise, photonic-electronic, signal processing. This technology is capable of high-speed, real-time signal correlation/processing by exploiting RF-photonics, ultra-stable optical frequency combs and high precision electronics.

Full Description

Signal processing is an important technology for both aeronautics and satellite communication. Unfortunately, current methods of signal processing are often sub-optimal or inadequate. Conventional signal processing techniques are limited by electronic signal bandwidth (< 40 GHz) and function poorly in applications requiring equivalent bit resolution at high speeds (<5 bit at 10 GHz). Furthermore, conventional signal processing techniques are unable currently to achieve signal correlation at high speeds. Given these limitations, there is a need for more effective signal processing methods.

Researchers at the University of California, Davis have developed a method for improved signal processing. It uses ultra-wideband, high precision, photonic-electronic technologies, resulting in high-speed, real-time, signal correlation and processing. This method of improved signal processing utilizes RF-photonics, ultra-stable optical frequency combs and high precision electronics. This method can scale its bandwidth up to THz and higher frequencies while still achieving high equivalent bit resolutions (ENOB as high as 10). It is also capable of optical correlation of high bandwidth signals (> 100 GHz). This improved signal processing technology allows for efficient analog-to-digital conversion, as well as real-time, photonic-electronic, processing.
