Abstract
An optical notch filter includes a particle layer including nano-particles in a substrate material. The nano-particles are arranged in one or more arrays to provide a nano plasmonic absorption of radiation having a wavelength of 532 nm incident on the filter. The filter exhibits a radiation absorption profile with an absorption maxima of at least 99% at 532 nm for an angle of incidence of between +50° and −50°, and has a full width half maxima transmission of less than 15 nm.
