    PAIR distinguished lecture series : three decades riding the photonic crystal fibre wave

    PAIR distinguished lecture series : three decades riding the photonic crystal fibre wave

    The lecture commenced with a warm welcome and brief speaker introduction by Prof. CHEN Qingyan, Director of PAIR. Prof. Russell kickstarted his presentation by giving a brief overview of the historical development of photonic crystal fibre (PCF), highlighting how advancements in optical fibres, Bragg scattering, photonic bandgaps and drawing towers laid the foundation for PCF breakthroughs. Prof. Russell shared that he proposed in 1991 a glass fibre with a periodic array of microscopic hollow channels running along its length might guide light in novel ways, and many PCFs emerged from drawing towers at universities in subsequent years. Next, he elaborated on the advantages of PCF, explaining how it offers enhanced control over the propagation light, and how this property has enabled valuable applications. He shared his research in light-guiding PCF, hollow core PCF filled with gas, and twisted PCF, reviewing how some of the scientific discoveries made possible by PCF have evolved into real-world applications.
