Abstract
A wavelength-selective optical switch includes a beam-splitting device and a plurality of wavelength tunable filters. The beam-splitting device distributes input optical signals to the plurality of wavelength tunable filters so that the optical signals entering each of the plurality of wavelength tunable filters have all wavelengths of the input optical signals.
