The invention concerns a process comprising the following steps: injecting, in an optical fiber, N time limited replica optical signals at distinct frequencies, each replica signal being temporally shifted relative to the other replica signals; then propag ...
Optical fibers have reshaped the technological landscape, from optical networks and high-speed data communication to in situ imaging and non-invasive surgery methods. The revolution allowed by these fibers has been made possible by its fabrication method, ...
The spectra of Brillouin scattering processes in optical fibers are affected by temperature, axial strain, and other quantities of interest. This dependence forms the basis for optical Brillouin scattering based optical fiber sensors. Since the first propo ...
Keeping up with our constantly connected lifestyle of instant messages and video streaming has its repercussions. Data centers have been gobbling up resources becoming a significant share of the energy used worldwide. To keep up with demand and curb the en ...
Since the invention of optical fiber cable data transmission using light has become ubiquitous in the past years. Nonlinear optical effects, which are hardly noticed in our daily life, have become crucial and highly influential for the design and performan ...
Modulation instability is thoroughly investigated and a simple analytical model for its power critically modifying the wave properties in terms of system parameters is derived and experimentally validated. The differences on the modulation instability gain ...
The ability to process optical signals without passing into the electrical domain has always attracted the attention of the research community. Processing photons by photons unfolds new scenarios, in principle allowing for unseen signal processing and comp ...
The possibility to directly realize all-optical delay lines in optical fibers has triggered efforts of research during the past decade, with few practical outcomes. The reason is fundamental, caused by the unescapable relation between delay and distortion. ...
Brillouin gain is observed in hollow core fibers filled by standard gases at high pressure. This enables all interactions based on stimulated Brillouin scattering to be realized in hollow core fibers, such as amplification, optical signal processing and di ...
