A nanoscale optical radiation source for optoelectronic chips has been created at the Alferov St. Petersburg Academic University (part of the NTI Competence Center "Photonics"). This was reported by the university's press service.
The source is a nanoantenna. It was created using femtosecond laser pulse printing on a gold film.
The proposed sources have a tunable wavelength without the use of modulators. It is sufficient to implement an array of nanoantennas and connect tunnel contacts with a size of 1-2 nm, which is significantly thinner than a human hair, so that at this stage it is possible to tune the radiation length for fast information transfer.
The new technology will allow placing a large number of nanosources in a small area. This will provide an advantage in performance and functionality compared to traditional methods.
