MIT researchers have made a significant breakthrough in nanophotonics, the manipulation of light at the nanoscale. A new platform developed by the team enables the creation of ultracompact optical components with increased efficiency and dynamic tunability.
The platform is built using established materials such as silicon, silicon nitride, and titanium dioxide, which are used to create structures like waveguides, resonators, and photonic crystals. These conventional materials have limitations that impede further miniaturization and functional complexity. However, the new platform addresses these limitations by enabling switching between optical modes.
The researchers’ achievement is significant because it allows for the creation of reprogrammable and responsive devices. This capability, which was previously difficult to achieve, has the potential to unlock further advancements in both nanophotonics and emerging quantum materials.
Professor Riccardo Comin, lead researcher on the project, believes that integrating emerging quantum materials with established nanophotonic architectures will foster progress in both disciplines. The new platform’s dynamic capabilities position it as a promising foundation for future optical technologies requiring adaptable and reconfigurable functionalities.
The breakthrough has the potential to broaden the applications of nanophotonic devices, moving beyond compact and efficient functionality to also responding dynamically to external stimuli. This research is published in the July 8th issue of Nature Photonics.
