Recent new methods in photonic signal processing based on stimulated Brillouin scattering (SBS) are presented. These include the realization of microwave photonic instantaneous frequency measurement systems that can simultaneously measure multiple-frequency signals while achieving very high resolution and wide frequency measurement range; and the characterisation of high-resolution bandpass filters...
Photonic signal processing offers a new powerful paradigm for processing high speed signals, due to its inherent advantages of wide bandwidth and immunity to electromagnetic interference. Microwave photonic frequency conversion is essential in wide-ranging optical-wireless system applications, and with the ever-increasing drive to higher operating frequencies, microwave photonic mixers, filters and...
Photonic signal processing offers a new powerful paradigm for processing high bandwidth signals, overcoming inherent electronic limitations. It opens new capabilities for realising high-resolution performance and programmable operation, while being inherently compatible with fibre optic microwave systems that integrate with wireless antennas. Recent new methods in wideband signal processors including...
A new photonic signal processor that is tunable, and which can also generate multiple taps including bipolar taps, is presented. The technique offers scalability, and is efficient because it uses wavelength re-use. Experimental results demonstrate a wide fractional tuning range of 35% for the filter and operation with high FSR.
A new photonic signal processor with wavelength reusability that can generate multiple taps including bipolar taps, is presented. It features coherence-free operation, and offers the ability of providing scalability and reconfigurability.
