The demand from exascale computing has made the design of high-radix switch chips an attractive and challenging research field in EHPC (exascale high-performance computing). The static power, due to the thermal sensitivity and process variation of the microresonator rings, and the cross talk noise of the optical network become the main bottlenecks of the network’s scalability. This paper proposes the analyze model of the trimming power, process variation power, and signal-to-noise ratio (SNR) for the Graphein-based high-radix optical switch networks and uses the extra channels and the redundant rings to decrease the trimming power and the process variation power. The paper also explores the SNR under different configurations. The simulation result shows that when using 8 extra channels in the 64×64 crossbar optical network, the trimming power reduces almost 80% and the process variation power decreases 65% by adding 16 redundant rings in the 64×64 crossbar optical network. All of these schemes have little influence on the SNR. Meanwhile, the greater channel spacing has great advantages to decrease the static power and increase the SNR of the optical network.

At the present time, developing of autonomous laser systems requires increasing of the output power of the laser sources used in composition of those systems and at the same time reducing of the energy usage in the system. The possibility of increasing output peak power of pulsed laser sources by using the method of synchronous non-coherent beam combining in ring fiber-optic delay line is considered by authors. Objective of this work was estimating energy effectiveness of laser systems, which based on this method.General constructing method of the laser pulsed laser source with ring fiber delay line is considered, its block diagram and the general operating principle of similar systems are presented. Two versions of laser systems based on the described method of beam combining are presented: using an optical combiner and an optical switch; using fiber welding instead of a combiner and an optical switch. The graphical dependence of the energy effectiveness on the number of circulations in ring fiber-optic delay line is obtained for both versions of laser systems.As a result of the analysis of the considered devices operation, it was shown that considered systems allow to obtain increasing the peak power of a laser pulse without increasing the power supply, also the system, that use welded fi instead of the optical combiner, has greater effi than system with optical combiner.
