Patent ID: 6873767

Claim:
A wavelength-multiplexing connector comprising: a single optical fiber for transmitting a plurality of optical signals having different wavelengths; a wavelength-multiplexer optically coupled to said optical fiber and optically separating a signal of a particular wavelength from the plurality of optical signals; and a jointing mechanism for connecting said wavelength-multiplexer with a transmitting and receiving part having an optical emitting device and optical receiving device; wherein said wavelength-multiplexer comprises: a first light waveguide coupled to said optical fiber and formed on a substrate; a wavelength division multiplexing filter structure formed on the substrate, wherein the filter structure separates a signal having a particular wavelength at an angle of about 90-degrees from the first light waveguide; and a second light waveguide through which the separated signal of the particular wavelength is transmitted; and wherein the filter structure comprises a filter provided midway of said first light wave guide, and a mirror for reflecting a signal, separated by said filter, at an angle of about 90-degrees in the course of said second light waveguide.
