Abstract
An optical device incorporates into the same physical structure the functionality of two or more wavelength selective switches. The wavelength components associated with the first optical switch are isolated from the wavelength components associated with the second optical switch by their spatial displacement along one axis on a programmable optical phase modulator. Remaining crosstalk between the components is reduced by spatially separating the components of the two wavelength switches having the same wavelength along another axis of the programmable optical phase modulator.
