New optical switch could lead to ultra-fast all-optical signal processing

An artist’s illustration of an optical switch, dividing light pulses according to their energies. Credit: Y. Wang, N. Thu and S. Zhou Caltech engineers developed a switch, one of the most fundamental components in computing, using optical rather than electronic components. The development could contribute to efforts to achieve ultra-fast all-optical signal processing and computation. …
