ABSTRACT:
An optical wavelength-division multi/demultiplexer for use in an optical multiplex communication, comprises a transparent substrate having opposite sides. A transmission off-axis diffraction grating is formed on one side of the substrate, for passing light incident thereon while diffracting and converging the same. A light reflecting element such as a transmission off-axis diffraction grating or flat specular reflection surface is provided on the other side of the substrate, for reflecting the light diffracted by the transmission off-axis diffraction grating toward the transmission off-axis diffraction grating.
