ABSTRACT:
The present invention relates to an optical fiber wavelength multiplexing or demultiplexing device comprising.
The multiplexer comprises input fibers (101 to 105) designed for carrying luminous beams at different wavelengths (.lambda.1, .lambda.2, . . . , .lambda.n), an output fiber (161) designed for carrying the whole set of such luminous beams, a dispersing system (107) receiving luminous beams from the input fibers (101 to 105) in an input plane and generating superimposed luminous beams designed for the output fiber (161) in an output plane.
A converging lens array (171 to 175) is located in the input plane, whereas a lens corresponds to each input fiber and whereby the said input fiber is placed in the focal point of the said lens.
The demultiplexer comprises the same elements, whereas the roles of the fibers and input/ouput planes are reversed.
