High heat flux component manufacture is the critical technology for the current fusion experimental devices and fusion reactors in the future since it will face fusion plasma directly and endure high flux particle irradiation and huge heat deposition from core plasma. Be/CuCuZr/ss, W/CuCrZr and CFC/CuCrZr modules have been selected as the high heat flux(More)
Slow light delay based on all-optical wavelength conversion using four-wave mixing (FWM) and dispersion medium is experimentally studied. Firstly, all-optical wavelength conversion with band-width of 28.4nm (from 1549.3nm to 1520.9nm) by FWM in 1500m dispersion flattened highly nonlinear fiber (DF-HNLF) is realized. Then, the maximum delay of 12.0ns is(More)
SiC nanowires (NWs) are commonly prepared in a Si-C-N system, but its formation mechanism is not fully understood. High resolution transmission electron microscopy and electron energy loss spectroscopy observation recorded the growth process of how Si(3)N(4) NWs were transformed into SiC NWs, and demonstrated the validity of an intermediate template(More)
