Perovskite crystals adapted for use as Faraday rotators
Crystal materials used in solar cells have been discovered to be cheaper alternatives to manipulate laser light with potential application in telecommunications, medical diagnostics and consumer electronics.
Researchers in Australia have found a way to manipulate laser light at a fraction of the cost of current technology.
The discovery, published in Advanced Science, could help drive down costs in industries as diverse as telecommunications, medical diagnostics and consumer optoelectronics.
The research team, led by Dr Girish Lakhwani from the University of Sydney Nano Institute and School of Chemistry, has used inexpensive crystals, known as perovskites, to make Faraday rotators. These manipulate light in a range of devices across industry and science by altering a fundamental property of light – its polarisation. This gives scientists and engineers the ability to stabilise, block or steer light on demand.
