Abstract
A multiwavelength switch is provided. The switch includes at least one optical input for receiving an optical beam and at least two optical outputs. A dispersion element receives the optical beam from the optical input and spatially separates the optical beam into a plurality of wavelength components. A collimating element is provided for collimating the plurality of wavelength components. An actuatable optical arrangement receives the collimated plurality of wavelength components from the collimating element. The actuatable optical arrangement includes a digital micromirror device (DMD) from which at least one wavelength component is reflected at least twice before being directed to a selected one of optical outputs.
