The press service of the Institute of Semiconductor Physics of the Siberian Branch of the Russian Academy of Sciences (ISP SB RAS) spoke about the new development of a group of scientists from Russia and Belarus. We are talking about photodiodes for telecommunication systems of a new generation, capable of delivering a rapidly changing high-power current, converting it from high-frequency laser radiation. The developed high-power microwave photodiodes are relatively small for speed and can be used as key components in fiber optic communication lines.
In addition to the fact that the new technology developed at the ISP SB RAS does not require the conversion of a radio frequency signal into a digital one, it provides a wide bandwidth (from 10 GHz and higher), which is equivalent to transmitting tens to hundreds of gigabits per second over distances up to 100 km. In general, the technical characteristics of the new devices, according to their authors, are similar to those of components produced abroad, and since the IPP SB RAS has full ownership of the technology, if necessary, scientists are ready to change something in it.
In the near future, experts are going to talk about the results of the next step - the manufacture of a photodetector with an integrated amplifier. The researchers solve this problem together with their colleagues from Tomsk, armed with technological methods that were developed during the creation of the above-described high-power microwave photodiodes.
