WebAug 10, 2024 · An optical filter is an optical element that reduce the incident beam signal to a specific part of it, either reducing its intensity or reducing it to specific wavelength range or polarisation. An optical filter is often defined with an angle of incidence (AOI), a use at a different angle may shift the value of the cut-on/ cut-off wavelength by ... WebAn anti-aliasing filter (AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to satisfy the Nyquist–Shannon sampling theorem over the band of interest. Since the theorem states that unambiguous reconstruction of the signal from its samples is possible when the power of frequencies above the Nyquist frequency is zero, a brick wall …

A relatively new class of filters introduced around 1990. These filters are normally filters in reflection, that is they are notch filters in transmission. They consist in their most basic form of a substrate waveguide and a subwavelength grating or 2D hole array. Such filters are normally transparent, but when a leaky guided mode of the waveguide is excited they become highly reflective (a record of over 99% experimentally) for a particular polarization, angular orientations, …
