Development of an innovative photon nanowire for the production of optoelectronic chips

Russian scientists have developed an innovative photon nanowire designed to produce optoelectronic chips. This became known on August 1, 2024. This achievement was the result of the work of Nikita Solomonov, an employee of Alfer University, which is part of the consortium of the NTI Competence Center "Photonik."

According to the "Center for Competence of NTI" Photonics, "the new source of optical radiation has nanosamples and is intended for use in photon integrated circuits (FIS). A key feature of the development is the ability to integrate the source directly onto the chip near the waveguide, which significantly increases the data transfer rate in devices.

An innovative approach is to use tunnel contact with an array of nanoantennes in thin layers of gold. The use of such nanostructures made it possible to increase external quantum efficiency by more than 10 times compared to previous technologies. This opens up new perspectives for applications in optoelectronics and quantum technologies.

Previously, the use of such sources in mass production was limited due to low quantum efficiency. The proposed method of using nanoantennes created using femtosecond laser pulses on a gold film is compatible with industrial production technologies and significantly increases radiation efficiency.

An important characteristic of the developed sources is their tunable wavelength without the need for modulators. To implement this function, it is enough to create an array of nanoantennes and connect tunnel contacts measuring 1-2 nanometers. This approach allows you to change the length of radiation to quickly transmit information.

The new technology provides the ability to place more sources in a limited area, which gives an advantage in performance and functionality over traditional sources of optical radiation. This could be a significant breakthrough in the development of new technologies in the field of photonics and telecommunications.^[1]
