Self-assembled Photonic Cavities with Atomic-Scale Confinement
Researchers have developed a method for self-assembling photonic cavities with atomic-scale confinement, enabling extreme light confinement and opening up new possibilities for nanophotonic devices. The study, conducted by scientists at the Technical University of Denmark, combines surface forces and conventional lithography and etching techniques to create suspended silicon nanostructures with void features well below the diffraction limit. The researchers demonstrated the fabrication of waveguide-coupled high-Q silicon photonic cavities that confine telecom photons to 2 nm air gaps with an aspect ratio of 100, resulting in mode volumes more than 100 times below the diffraction limit. Scanning transmission electron microscopy measurements confirmed the sub-nanometer dimensions of the devices. The use of self-assembly in combination with planar semiconductor technology could lead to the development of a new generation of nanophotonic devices that combine atomic-scale confinement with the scalability of planar semiconductors.
