Optical Switching Layer for Rewirtable Volumetric Optical Disks
phase change DVD volumetric optical disk dual layer optical disk optical switching layer thermo-chromatic material
2011/11/28
Owing to the presence of out-of-focus recording layers in volumetric optical disks, laser energy is decreased in reading/writing the targeted active layer. A non-linear optical material as an optical ...
A volumetric optical disk that has multiple transparent films with optical switching layers is used as a recording medium to increase the number of recording layers. In the disk the optical switching ...
Feasibility Study on Topology Malleable Data Center Networks (DCN) Using Optical Switching Technologies
Networks network topology Switching circuit
2015/5/26
We recently presented a highly advantageous DCN architecture that supports on-demand, run-time topology malleability using WDM and optical space/wavelength switching technologies. We further investiga...
