Material Reduces Signal Loss, Boost Efficiency of Light-Based Devices

Facebook Twitter LinkedIn Email Comments
Photonic devices could see a reduction in optical signal loss as a result of the discovery of a plasmonic metamaterial that compensates for loss of light energy by using a semiconductor to act as a light emitter. Plasmonic metamaterials typically contain metals that absorb energy from light and convert it into heat, wasting a portion of the optical signal and lowering its efficiency. “ SEM images of a “lossless” metamaterial that behaves simultaneously as a metal and a semiconductor.
