Dynamically tunable, low-noise, discrete-time optical processing of high-speed signals

In today's society there is an unrelenting push for increasing bandwidth requirements. Thus the challenge arises to provide systems that can optimally condition high-speed signals. Many systems carry not only the desired information but also high level interference signals. Tunable interference mitigation is required to address different interferers actively while having minimal impact on the passband. The new dynamically tunable photonic signal processors in this project have important applications for science, business and security services. The results have widespread uses in enhancing fibre-fed distributed antenna systems, with national benefits in the fields of radioastronomy and radar systems in defence.
