Fiberguide Industries Inc., a Halma company, said it has been granted an exclusive license from TelAztec of Burlington, Mass., to develop Motheye AR (antireflective) nanostructures for use in fiber optic cable, specifically for high-power delivery applications. Motheye AR nanostructures were originally discovered by the observation of nocturnal insects, such as moths. Courtesy of Fiberguide Industries. Motheye AR nanostructures were originally discovered by the observation of nocturnal insects, such as moths. The compound eyes of these insects were found to reflect little or no light, regardless of the light’s angle of incidence. TelAztec used this observation to develop effective, randomized, AR nanostructures for use on glass substrates, which Fiberguide Industries will market under the trade name RARe Motheye. RARe Motheye coatings have damage thresholds that are far greater than AR coatings, Fiberguide said, close to that of silica fiber and three to seven times higher than standard AR coatings. The random AR surfaces have broad antireflection properties and operate over a large (about 400-nm) wavelength range compared to the narrow (about 50-nm) operating range for conventional AR coatings. Potential applications include medical systems, industrial lasers, directed energy, digital cinema projects and data array transmission.
