Research highlights<\/h2>\n

In this work, we report a new photonic approach that advances the state of the art in ultrafast optical signal acquisition and processing<\/strong>. In particular, we demonstrate an all-optical ultrafast user localisation method<\/strong> for beam-steered optical wireless communication, achieving update rates of 50 MHz<\/strong>. User position is encoded in optical wavelength and retrieved from the time delay between optical pulses<\/strong>, eliminating the need for high-speed electronics or digital signal processing and enabling a simple, low-cost, and energy-efficient solution<\/strong>.By combining high-speed photonic hardware<\/strong> with innovative signal processing concepts<\/strong>, the study demonstrates how optical-domain techniques can overcome fundamental bandwidth and latency limitations faced by conventional electronic systems.<\/p>\n

The results highlight the potential of photonics to enable real-time, high-throughput measurement and information processing<\/strong>, which is increasingly important for applications where speed, sensitivity, and scalability are critical.<\/p>\n

Why this matters<\/h2>\n

Ultrafast photonic technologies underpin a wide range of emerging applications, including:<\/p>\n
