Most conventional optical isolators rely on Faraday  rotation and are realized using micro\/nanofabrication  techniques, but it is not always straightforward to incorporate  magneto-optical crystals into these compact systems. Here, we report the  experimental demonstration of a reconfigurable all-optical isolator  based on optical excitation of a gigahertz guided acoustic mode in a  micrometre-sized photonic crystal fibre core. This device has remarkable  advantages over its passive counterparts, including a large dynamic  range of isolation, fast switching capability and reversibility, which  provide new functionality that is useful in various types of all-optical  systems. Devices based on similar physical principles could also be  realized in CMOS-compatible silicon on-chip platforms.<\/p>\n<h3>Related Images:<\/h3>","protected":false},"excerpt":{"rendered":"<p>Reconfigurable light-driven opto-acoustic isolators in photonic crystal fibre by P.
