A groundbreaking study published in \u201cNature Communications\u201d unveils a method for laser nanofabrication directly within silicon, with significant implications for the fields of nanophotonics, silicon photonics and 3D electronic-photonic integrated systems. The research, led by Asst. Prof. Onur Tokel from the Department of Physics and UNAM \u2013 National Nanotechnology Research Center showcases the ability to create the first controlled nanostructures deep inside silicon wafers, achieving feature sizes as small as 100 nm, marking a significant leap from the current state-of-the-art. <\/p>\n\n\n\n
\u201cOur approach is based on localizing the laser energy within a semiconductor material to an extremely small volume, such that one can exploit emergent field enhancement effects analogous to those in plasmonics. This leads to sub-wavelength and multi-dimensional control directly inside the material,\u201d explained Dr. Tokel. <\/p>\n\n\n\n
\u201cThat the researchers were able to achieve nano-scale features is spectacular,\u201d says Maxime Chambonneau, a researcher at the University of Jena, in Germany, who was not involved in the work. \u201cOur findings introduce a new nano-fabrication paradigm,\u201d explains Dr. Tokel. \u201cThe ability to fabricate at the nano-scale directly inside silicon opens up a new regime toward further integration and advanced photonics. We can now start asking whether complete three-dimensional nano-fabrication in silicon is possible. Our study is the first step in that direction.\u201d <\/p>\n\n\n\n
