Scientists at the Indian Institute of Science (IISc), Bangalore, have achieved a groundbreaking advancement in the manipulation of light on a microscopic scale, which could transform quantum communication, data encryption, and photonic devices. Led by Professor Jaydeep K. Basu, the research team collaborated with experts from Texas A&M University to merge colloidal quantum wells (CQWs) with dielectric metasurface resonators (MSRs), resulting in a silicon-based system that enhances light brightness by 12 times and narrows the spectral width of emitted light by 97%. This innovation allows light to travel up to 1 millimeter on a single chip, promising compact quantum devices. The researchers aim to integrate single photon emitters with MSRs for enhanced quantum cryptography and information processing. Their findings, published in Advanced Optical Materials, underscore IISc’s commitment to pioneering research in quantum technologies, offering exciting prospects for secure communication and advanced detection systems.
