From an article written by AZoNano:
A team of physicists from ITMO University (Saint Petersburg) and Moscow Institute of Physics and Technology (MIPT) has demonstrated the potential of silicon nanoparticles for effective non-linear light manipulation.
Their work lays the foundation for the development of novel optical devices with a wide range of functionalities. These silicon nanoparticles based devices would allow to transmit, reflect, or scatter incident light in a specified direction, depending on its intensity.
They could be integrated into microchips that would enable ultrafast all-optical signal processing in optical communication lines and the next generation optical computers.
