  • Optical wavelength converter
    Patent number: 6603592
    Abstract: An optical-to-optical wavelength converter for converting a plurality of optical bits from a first wavelength in a first wavelength band to a second wavelength in a second wavelength band. The optical-to-optical wavelength converter employs a directional coupler.
