We propose a scheme for real-time, joint time-frequency analysis of arbitrary continuous optical signals. Through phase-only linear operations, we demonstrate the recovery of ns-duration transient events, 22-GHz bandwidth operation, and sub-GHz resolution. Billions of Fourier transforms per second are computed without information loss.

The realisation of hollow-core fibres and nano-waveguides offers a unique opportunity to optimise the interactions between light and a gaseous medium. Stimulated Brillouin scattering is exploited to achieve unprecedented levels of amplification and to realise efficient all-optical processing.

We present a novel framework for robust inverse-design of semiconductor-foundry devices tolerant to standard fabrication variability. We designed and tested compact 50/50, 90/10, and 99/1 power splitters sampled across multiple wafers on a commercial silicon photonic process, demonstrating < ±2% deviation over 100 nm of bandwidth.

We propose a quality of transmission metric which unifies different performance-related metrics into one. Our metric presents advantages such as the reduction of stored and transmitted data, low controlled uncertainty and high monitoring speed, while it is compatible with an extended range of performance regimes.

We propose and experimentally demonstrate novel in-line control and management scheme for in-service end-to-end user connections with any signal protocol in the All-Photonics Network. AMCC signals based on subcarrier allocation yield remote control of user terminals without any optical/electrical conversion with link budget of 47.5-dB.
