Subwavelength Silica Wires Display <0.1 dB/mm Optical Loss

Facebook X LinkedIn Email
Researchers at Harvard University in Cambridge, Mass., Zhejiang University in Hangzhou, China, and Tohoku University in Sendai, Japan, have produced subwavelength-diameter silica waveguides that display optical losses of less than 0.1 dB/mm. The wires, which they reported in the Dec. 18/25 issue of Nature, may find uses in optical communications and sensing applications and as micro- and nanoscale research tools. The scientists have developed a two-step fabrication process to create the wires. They begin by drawing wires with diameters on the order of a micron from a silicon fiber. They...Read full article
