IT Home December, according to Russian Satellite News Agency, "Science Russian" Electronic Journal sent a document, Moscow Electronic Technology, Moscow National Normal University, with other Russian experts, common inventions for development new generation The chip of the photonic circuit.
Experts said that this invention can manufacture "non-volatile adjustable nano-photonic chip", which has been used for microelectronics production without additional upgrades.
Peter Lazieko, a senior researcher, Future Materials and Technology, Moscow Institute of Electronic Technology, said: "In the newly inventive chip, the surface of the silicon nitride microcontrol resonator is partially covered with a GST phase change material film. GST coating Phase changes, absorption can result in changes through the optical signals of the waveguide.The phase conversion can be triggered by a laser pulse through the waveguide. "
According to IT's home, the phase transition of this chip film occurs within 10 nanoseconds. The GST film is one of the best materials of the signals in the film waveguide element used in the telecommunications apparatus. Now, the expert team is optimizing the chip to increase the number of entered logic levels. In addition, experts are still looking for methods to design new optical integrated circuits and its entire set of systems.
