It is shown that wavelength-selective optical-fiber couplers can be made by choosing materials having appropriate dispersive characteristics. The wavelength-selective effect is caused by differential material dispersion of the optical fibers that compose the coupler. The 1.30–1.57-μm wavelength-division multiplexers/demultiplexers are designed by the use of optical-fiber couplers fabricated from dispersive materials.
