Editorial- Photonics for computing and computing for photonics

International audienceThe liaison between photonics and computing is a pillar of modern optics and subject of cutting-edge research for morethan half a century. As in many scientific disciplines, high-performance computational methods have become essentialfor describing, designing, interpreting and ultimately predicting an optical system’s behaviour, and today the wideavailability of high-performance photonic components is testimony of how computing has boosted the field of photonics.At the same time, photonic architectures offer fascinating possibilities for carrying out computations scaling beyondcomputing.
