Talk Title
Advances in Photonic Signal Processing
Talk Abstract

Photonic signal processing offers the prospect of overcoming a range of challenging problems in the processing of high-speed signals. Its intrinsic advantages of high time-bandwidth product and immunity to electromagnetic interference (EMI) have led to diverse applications. Photonic signal processing leverages the advantages of the optical domain to benefit from the wide bandwidth, low loss, and natural EMI immunity that photonics offers. Next generation global telecommunication platforms and emerging applications in radar and communications will require entirely new technologies to address the current limitations of electronics for massive capacity and connectivity. Microwave photonics, which merges the worlds of RF and photonics, shows strong potential as a key enabling technology to enable new paradigms in the processing of high speed signals that can overcome inherent electronic limitations. Photonic signal processors are intrinsically compatible with optical-wireless systems, and can provide connectivity with in-built signal conditioning, while also providing important advantages of EMI immunity.

Moreover, the integration of photonics on semiconductor material platforms that co-exist with CMOS electronics enables boosting the operating performance of future systems performing sensing and communications with the potential for implementing high bandwidth, fast and complex functionalities. This integration technology is driven by high bandwidth optical communications and massive deployment of low-cost optical interconnects for datacom. Recently there has been a strong drive to realise photonic integrated circuits using Silicon Photonics. This is particularly attractive because it enables a CMOS-compatible fabrication that enables the integration of combined photonic and electronic functions on one chip. It also makes possible a cost-effective implementation with reduced footprint, power and weight. 

Recent advances in integrated photonic signal processing are presented. This includes versatile beamforming and beam steering systems for phased array antennas, sideband modulation suppression techniques for achieving dispersion-free microwave-optical links, optical vector network analysers with high resolution, broadband tunable filters using optical micro-ring resonators, multi-function processors, and integrated photonic sensors that demonstrate extremely high sensitivity.  These microwave photonic processors provide new capabilities for the realisation of high-performance signal processing.
