Abstract:
At least one diffraction element is used to diffract light of multiple wavelengths into different wavelength components. Instead of moving the diffraction element as in certain prior filters, light from the at least one element is reflected back towards the at least one element so that light is diffracted at least twice by the at least one element. The reflection is such that at least one selected wavelength component of said wavelength components will pass from an input port to an output port or to another device.
