ABSTRACT:
An optical apparatus for converting an incoming array of light beams by interchanging the horizontal and vertical components of each beam, the apparatus having a series of grooves, one groove for each incoming beam, where each groove comprises two reflecting surfaces: a first reflecting surface operating to intercept the corresponding beam and reflect it to a second reflecting surface along a first path of travel, that is folded with respect to the incoming beam's direction of propagation, while rotating one of the beam's azimuths, and the second reflecting surface operating to intercept the beam reflected off the first surface and to direct it along a second path of travel, folded with respect to the first path of travel, while rotating the beam's other azimuth.
