Researchers from Chalmers University of Technology (Sweden) have developed an on-chip optical amplifier that increases data transmission speeds tenfold compared to current systems. The device consists of spiral channels made of silicon nitride and covers a range of 300 nanometers compared to 30 in analogs. Peter Andrekson, the lead researcher, stated: 'The main advantage is the combination of record-wide bandwidth with low noise levels.' The device operates in the range of 1400-1700 nanometers. By altering the structure of the channels, the amplifier can be adapted for visible light (400-700 nm) and infrared radiation (2000-4000 nm). The technology will first be integrated into internet infrastructure, then into medical equipment. Scientists predict that within 5-10 years such chips will become the foundation of fast internet and precise diagnostic methods for diseases.
