Research by Rana Biswas, ECpE professor, and Akshit Peer, ECpE PhD student, published in Nanoscale, was featured in Optics and Photonics News last week.
Biswas and Peer’s work demonstrates a technique for achieving an optical transmission, with modeled electric-field enhancements as high as a hundredfold, using a continuous film of gold on a corrugated, “nanocupped” substrate. The technique only requires soft-lithography fabrication and can create large-area films.
According to Peer, the ability both to inexpensively create these large-area films and to straightforwardly measure their optical properties makes them a great platform for experiments and applications in plasmonics, sensing, photovoltaics, etc.
