The analogue of tsunami for telecommunication
Development of electronics and communication requires hardware capable of increasingly larger precision, ergonomics and throughput. For communication and GPS navigation satellites, it is of great importance to reduce the payload mass as well as to ensure signal stability. Last year, researchers from Moscow State University (MSU), together with their Swiss colleagues, performed a study aimed at certain improvements in this direction. In a paper published in Nature Photonics, the scientists reported that the primary source of noise in microresonator-based optical frequency combs (broad spectra composed of a large number of equidistant narrow emission lines) is related to non-linear harmonic generation mechanisms rather than by fundamental physical limitations and is, in principle, reducible.
