Abstract
The tuner has constituent component for constructing a tunable or switchable spectral filter, including single and multiple stage filters and fitters without intermediate polarizer, over a wavelength range. It has elements arranged in cascade along a light beam axis including a dispersive polarization rotator that has its rotation angle ρ(λ) varying as a function of light wavelength lambda over the wavelength range.
