Now IQUIST member Gaurav Bahl and his research group have designed a simple, compact photonic circuit that uses sound waves to rein in light. For practical use, scientists and engineers need to miniaturize quantum devices, which requires re-thinking certain components for harnessing light. Currently, such early quantum technology is limited by size-state-of-the-art systems would not fit on a dining room table, let alone a chip. For example, scientists use laser light to precisely control atoms, turning them into ultra-sensitive measures of time, acceleration, and even gravity. Given its broad utility, it’s no surprise that light plays a critical role in enabling 21 st century quantum information applications. On-chip optical isolators for 780 nm and 1550 nm wavelengths, fabricated in lithium niobate at the University of Illinois Urbana-Champaign. Here on earth, controlling light lets us send data from one side of the planet to the other.
It can travel across galactic distances and collide with our atmosphere, creating a shower of particles that tell a story of past astronomical events. 25, 2021 - Light offers an irreplaceable way to interact with our universe.
