Technique enables newfound control of light polarization at any angle

Wednesday, July 27, 2016 - 07:41 in Physics & Chemistry

Polarizing filters produce richer, less reflective images by limiting vibrating light waves to one specific orientation. However, these filters only work with light that is reflected from a certain angle. An A*STAR-led team now report that arrays of silicon nanodisks can polarize light at any angle, and into any desired orientation—a finding that opens the way to improved photonic control over ultra-thin optical devices.
