摘要： An optical filter includes a first layer including a first notch filter arranged to attenuate electromagnetic radiation having a first wavelength λ1 incident normally thereupon. The optical filter includes a second layer including a second notch filter arranged to attenuate electromagnetic radiation having a second wavelength λ2 incident normally thereupon. The first wavelength λ1 and the second wavelength λ2 are different. The second layer is stacked upon the first layer. In use, the first notch filter attenuates the electromagnetic radiation having a predetermined wavelength λ incident thereupon at a first angle of incidence θ1 and the second notch filter attenuates the electromagnetic radiation having the predetermined wavelength λ incident thereupon at a second angle of incidence θ2, wherein the first angle of incidence θ1 and the second angle of incidence θ2 are different.

摘要： There is provided a method for fabricating a waveguide master grating imprint tool. The method comprises: coating a substrate with at least one photoresist layer; selectively exposing a first diffraction grating master profile onto a first area of the at least one photoresist layer; selectively exposing a second diffraction grating master profile onto a second area of the at least one photoresist layer; and processing the substrate to form the first diffraction grating master profile and the second diffraction grating master profile. Each of the first diffraction grating profile and the second diffraction grating profile comprises an edge between the substrate and the respective grating profile that is substantially perpendicular to the substrate surface and each of the edges is substantially the same height as a maximum depth of the first diffraction grating master profile and the second diffraction grating master profile
