Light offers an irreplaceable way to interact with our universe. It can travel across galactic distances and collide with our atmosphere, creating a shower of particles that tell a story of past astronomical events. Here on earth, controlling light lets us send data from one side of the planet to the other.<\/p>\n

Given its broad utility, it\u2019s no surprise that light plays a critical role in enabling 21st century quantum information applications. For example, scientists use laser light<\/a> to precisely control atoms, turning them into ultra-sensitive measures of time, acceleration, and even gravity. Currently, such early quantum technology is limited by size\u2014state-of-the-art systems would not fit on a dining room table, let alone a chip. For practical use, scientists and engineers need to miniaturize quantum devices<\/a>, which requires re-thinking certain components for harnessing light.<\/p>\n

Now IQUIST member Gaurav Bahl and his research group have designed a simple, compact photonic circuit that uses sound waves<\/a> to rein in light. The new study, published in the October 21 issue of the journal Nature Photonics<\/i>,<\/i> demonstrates a powerful way to isolate, or control the directionality of light. The team\u2019s measurements show that their approach to isolation currently outperforms all previous on-chip alternatives and is optimized for compatibility with atom-based sensors.<\/p>\n","protected":false},"excerpt":{"rendered":"
