Using a two-color time-resolved Faraday rotation measurement technique, researchers at the University of California, Santa Barbara, have observed the transfer of electron spin information between molecularly linked CdSe quantum dots at room temperature. The work, which they reported July 31 online on Sciencexpress, suggests that such structures may be suitable for the fabrication of spintronic devices for applications such as quantum information processing. To produce the quantum-dot assemblies, Min Ouyang and David D. Awschalom immersed functionalized fused silica substrates in a solution...Read full articleRelated content from Photonics MediaArticlesDiffractive Optical Network Enables Snapshot Multispectral ImagingUCLA researchers led by Aydogan Ozcan and Mona Jarrahi have developed a multispectral imaging technology capable of turning a monochrome sensor into a multispectral one.
