Abstract

A wavelength division multiplexer for multimode fibers is described which makes use of a 45° incidence dichroic filter as dispersive element and of GRIN rod lenses as collimating/ focusing optics. The device has been designed in two configurations: one constituted by a metallic cube with three lateral holes for lens ended fibers coupling and a slot in a diagonal plane for the insertion of the filter; the other one consisting of two glass prisms suitably designed between which the filter is interposed, while the GRIN lenses are directly cemented on the prism sides. Details on the two device assembling and characterization measurement are reported.
