Chaos

In this work, published in Laser Photonics Review we report on the all-optical control of chaotic optical resonators based on a silicon on insulator (SOI) platform. We show that simple non-chaotic cavities can be tuned to exhibit chaotic behaviour via intense optical pumping, inducing a local change of refractive index. To this extent we have fabricated a number of devices and demonstrated experimentally and theoretically that chaos can be triggered on demand on an optical chip.   We show that the degree of chaos supported by a microcavity can be controlled dynamically using light itself. We start with a square (non-chaotic) cavity obtained on SOI.… Read More »Ultrafast All-Optical Order-to-Chaos Transition in Silicon Photonic Crystal Chips
