Microwave Photonics Signal Processing
Microwave photonics (MWP) is an emerging interdisciplinary area that investigates the interaction between microwave and optical waves, for widespread applications ranging from defense applications, such as radar and electronic warfare systems, to civil applications, such as wireless and satellite communications, imaging and instrumentation. Thanks to the inherent advantages of optics, such as high speed, broad bandwidth and reduced electromagnetic interference, various novel photonic techniques have been developed for efficient generation, distribution, control, processing and analysis of microwave signals, thus enhancing and enabling new functionalities that are very complex or challenging to achieve only in the microwave domain due to the limited speed and bandwidth of electronic devices.
Recent research efforts within the area of microwave photonics include photonic generation and processing of microwave and millimetre-wave signals, photonically assisted phased array antennas, radio-over-fiber systems, arbitrary microwave waveform generation, and photonic analog-to-digital conversion (ADC). At Kent, we are investigating DFT-based microwave photonics signal processing applications, with emphasis on microwave arbitrary waveform generation, microwave photonic filters, microwave spectrum sensing, and optical pulse characterization and shaping.
