Super-oscillatory optical needle for heat-assisted magnetic recording

Super-oscillatory optical needle for heat-assisted magnetic recording
Super-oscillatory optical needle for heat-assisted magnetic recording
We demonstrate an alternative to plasmonic focusing, a super-oscillatory focusing lens capable of producing a 51nm spot for optical heating in heat assisted magnetic recording using a diode laser operating at 473 nm wavelength.
