  • Patent number: 6845186
    Abstract: An optical circuit is designed with demultiplexing and optical detection functionality with minimal crosstalk. An Nth order harmonic generation device is positioned before the demultiplexer to either convert the frequency or down convert the wavelength of the demultiplexed light wave by N-times. Upconverting the multiplexed signal at the receiver station is performed by either simultaneously upconverting N-times to create N times the original spacing between each optical channel or by upconverting the frequency of one optical channel at a time.
