NETWORKS OF COUPLED RANDOM LASERS WITH SPATIALLY LOCALISED FEEDBACK

摘要

The present invention generally relates to a random laser coupling system comprising at least three spatially distanced random-lasing light-scattering centres and at least two laser-pumping stripes, wherein each laser-pumping stripe connects two of said light-scattering centres, configuring at least two random laser resonators with spatially localised feedback. Advantageously in the invention, one of the at least three light-scattering centres is connected to two of the laser-pumping stripes, so that the at least two random laser resonators share one of the light- scattering centres. The invention also refers to a method for coupling random lasers comprising the use of said random laser coupling system. The use of the coupling enables a non-linear influence of a resonator in a neural network that can be used for computing.
