  • Although TCOs hold promise for high-speed data processing, there are still issues of power consumption and optical loss that need to be addressed before the practical implementation of devices based on these materials. (utwente.nl)
  • Shear and extensional flow fields are ubiquitous in the manufacture, processing and use of these everyday materials and yet, typical experimental techniques, like small angle scattering, only provide information about the quiescent or time-averaged state. (lu.se)
  • In this study, we report the first all-optical temporal integrator in a monolithic, integrated platform. (nature.com)
  • A comprehensive study of the underlying nonlinear processes and bifurcation analysis leads to a better understanding of the observed behavior. (wias-berlin.de)
