Dr Kristin Pfeiffer, Pallabi Paul, and Dr Adriana Szeghalmi have developed conformal coating processes for functionalising strongly curved optics

A rendering of the experimental setup used. Light is reflected down to the nanostructure of molybdenum disulfide (yellow and teal lattice) and PZT (blue and green). Wavelengths reflecting from the surface are captured by the top detector as transmitted wavelengths pass through the PZT to the bottom detector. (Image: Hong et al.)

Smaller, more versatile optical filters on the horizon

Researchers could spur the development of smaller, more versatile optical filters that are especially adept at playing a trick of the light
