"Indium Phosphide Nanocavity Achieves Sub-Wavelength Light Confinement"
Researchers at the Technical University of Denmark have developed a new III-V semiconductor nanocavity that can confine light at levels below the diffraction limit, demonstrating extreme dielectric confinement (EDC). This achievement could lead to advancements in photonic devices, quantum communication, and sensing, as well as improved energy efficiency in data centers and computers. The nanocavity, fabricated in indium phosphide, exhibits a mode volume an order of magnitude smaller than previously demonstrated in III-V materials, enhancing light-matter interaction and enabling potential applications in various fields, including advanced imaging and environmental monitoring.
