1. A wavelength selective switch for switching wavelengths from one or more optical signals, the signal comprising one or more optical wavelengths, each constituting a work piece, the wavelength selective switch comprising:

  • a plurality of fiber ports arranged in a fiber port array;

    a plurality of optical elements operable with said plurality of fiber ports;

    a dispersive element operable with said plurality of fiber ports to separate at least one optical signal into a plurality of wavelength components; and

    a switching element operable with the plurality of wavelength components and controllable to guide a selected one of the plurality of wavelength components to a selected one of said plurality of fiber ports,wherein at least one of said plurality of optical elements, said dispersive element, and said switching element affects an optical property of at least one optical signal in a first plane, and wherein said at least one of said plurality of optical elements, said dispersive element, and said switching element does not substantially affect said optical property in a second plane, said first plane being generally orthogonal to said second plane.
