Abstract
A free space multiport wavelength router for directing channels of a received WDM optic signal to a plurality of output ports. The inventive router includes a lens which receives an incoming WDM signal and focuses the signal on a grating for angular displacement, as a function of wavelength, of the individual channels in the WDM signal. The angularly displaced channels are then collimated by the lens and provided to an array of optical elements. The array is oriented relative to the lens so that each element in the array receives and imparts an orthogonal displacement to a corresponding channel relative to the dispersement direction provided by the grating. The othogonally-dispersed channels are then reflected back to the grating and are output to select output optic fibers.
