Researchers from Monash University have developed a breakthrough nanoscale circuit that can generate, direct, and read light-based information, all on a single chip.
The new technology, developed by scientists in the Monash School of Physics and Astronomy, brings together cutting-edge materials and nanotechnology to overcome a long-standing challenge in "valleytronics," an emerging field that could underpin faster, more energy-efficient computing and quantum technologies.
For the first time, the team has demonstrated a fully integrated system that can generate special light signals, guide them in precise directions, and convert them into electrical signals, all within a compact, chip-based device.
These light signals carry information using a property known as the "valley degree of freedom," a quantum characteristic of materials that can be harnessed to encode and process data in entirely new ways.
