Effects of picosecond Laser Power variation on Laser-induced changes of titanium
2016 IEEE International Conference on Manipulation Manufacturing and Measurement on the Nanoscale (3M-NANO), 2016Co-Authors: Chengjuan Yang, Yanling Tian, Zhen YangAbstract:In order to understand the influence of picosecond Laser parameter variation on Laser-induced changes of titanium, the sheet surfaces of titanium were irradiated by picosecond Laser pulses with different average Laser Power in this work. Then X-ray photoelectron spectroscopy (XPS) and transmission electron microscope (TEM) were used to analyze the influences of average Laser Power variation on final chemical composition and microstructure of the ablated titanium, respectively. With the average Laser Power increasing from 4mW to 30mW, it is found that the main ablation products of titanium were both TiO2 and TiC, and the contents of TiO2 and TiC among ablation products continuously rose; meanwhile, the content ratio of TiO2 to TiC kept falling. Besides that, the increase of average Laser Power intensified the amorphization degree of microstructure of ablated titanium. Finally, it is concluded that the increased Laser fluence resulted from average Laser Power increasing, which intensified the heat accumulation effect on titanium surfaces. Then, the thermal and mechanical damages were deepened and enlarged in the Laser ablated zone.

Runtime Management of Laser Power in Silicon-Photonic Multibus NoC Architecture
IEEE Journal of Selected Topics in Quantum Electronics, 2013Co-Authors: Chao Chen, Ajay JoshiAbstract:Silicon-photonic links have been proposed to replace electrical links for global on-chip communication in future many-core processors. Silicon-photonic links have the advantage of lower data-dependent Power and higher bandwidth density, but the high Laser Power can more than offset these advantages. We propose a solution to manage Laser Power of silicon-photonic network-on-chip (NoC) in many-core system. We present a silicon-photonic multibus NoC architecture between private L1 caches and distributed L2 cache banks which uses weighted time-division multiplexing to distribute the Laser Power across multiple buses based on the runtime variations in the bandwidth requirements within and across applications to maximize energy efficiency. The multibus NoC architecture also harnesses the opportunities to switch OFF Laser sources at runtime, during low-bandwidth requirements, to reduce Laser Power consumption. Using detailed system-level simulations, we evaluate the multibus NoC architecture and runtime Laser Power management technique on a 64-core system running NAS parallel benchmark suite. The silicon-photonic multibus NoC architecture provides more than two times better performance than silicon-photonic Clos and butterfly NoC architectures, while consuming the same Laser Power. Using runtime Laser Power management technique, the average Laser Power is reduced by more than 49% with minimal impact on the system performance.
