Optical High Density Nanolaser Array Driver Researchers have developed a new all-optical method for driving multiple high-density nanolaser arrays using light traveling down a single optical fiber. The optical driver creates programmable patterns of light via interference. Credit: Myung-Ki Kim, Korea University New all-optical pumping chip-based nanolaser technology could aid in meeting the ever-growing need to move more data faster. A new all-optical approach for driving multiple highly dense nanolaser arrays has been developed by researchers in Korea. The method could enable chip-based optical communication links that process and move data much faster than current electronic-based devices. “The development of...

Nanolaser Device Detects Cancer in Single Cells Using an ultrafast, nanoscale semiconductor laser, investigators at Sandia National Laboratories in New Mexico, have discovered a way of rapidly distinguishing between malignant and normal cells. Moreover, this new technique has the potential of detecting cancer at a very early stage, a development that could change profoundly the way cancer is diagnosed and treated. Reporting its work in the journal Biomedical Microdevices, a team of researchers led by Paul Gourley, Ph.D., described the methods it used to construct a device that can flow cells one at a time past an ultrafast laser, and...
