Design and characterization of such ultra-high capacity systems requires numerical techniques capable of dealing with vast amounts of data simulating nonlinear transmission and interaction of signals propagating in numerous spatial channels at different wavelengths, thus imposing serious challenges with respect to both, memory requirements and computation performance. We discuss how massive-parallel computation capabilities of modern Graphical Processing Units (GPUs) can be utilized to develop efficient numerical algorithms and present assessment results for the GPU-assisted SDM-capable implementation in the existing simulation environment of VPItransmissionMaker Optical Systems.

The conditions of stable laser operation are studied. It is proposed to use an additional aperture as an element of negative feedback for the stabilisation of passive mode locking. Practical recommendations concerning the optimisation of a femtosecond laser are given.

Due to the large number of varying, partly unknown parameters, this is only feasible with the help of ...
