Photonic instantaneous frequency measurement of wideband microwave signals
We propose a photonic system for instantaneous frequency measurement (IFM) of wideband microwave signals with a tunable measurement range and resolution based on a polarization-maintaining fiber Bragg grating (PM-FBG). Firstly, in order to be insensitive to laser power fluctuation, we aim at generating two different frequency to amplitude characteristics so that we can normalize them to obtain ...
متن کاملPhotonic Implementation of an Instantaneous Frequency Measurement
With the rapid and ongoing developments in telecommunication and electronic warfare technology, faster and more flexible systems are in demand. Wideband signal processing is thus needed to implement such systems. Microwave photonics has been introduced as a tool for achieving such ultra broadband signal processing. Instantaneous Frequency Measurement (IFM) receivers play an important role in el...
متن کاملPhotonic-assisted wideband phase noise measurement of microwave signal sources
ELECT A photonic-assisted scheme for the phase noise measurement of microwave signal sources is proposed based on the optical delay-line method. In the proposed scheme, all the microwave signal processing is implemented in the optical domain, and the electrical devices that would limit the operation bandwidth and measurement sensitivity are avoided, leading to a large operation bandwidth and a ...
متن کاملMicrowave Photonics: Photonic Generation of Microwave and Millimeter-wave Signals
Techniques to generate microwave and millimeter-wave (mm-wave) signals in the optical domain will be reviewed, with an emphasis on the techniques for microwave generation based on heterodyne of two phase correlated wavelengths.
متن کاملWideband dynamic microwave frequency identification system using a low-power ultracompact silicon photonic chip
Photonic-based instantaneous frequency measurement (IFM) of unknown microwave signals offers improved flexibility and frequency range as compared with electronic solutions. However, no photonic platform has ever demonstrated the key capability to perform dynamic IFM, as required in real-world applications. In addition, all demonstrations to date employ bulky components or need high optical powe...
