OPTICAL WAVELENGTH CONVERTER

摘要

An optical wavelength converter for converting a plurality of optical bits from a first wavelength to a second wavelength. The optical wavelength converter employs a directional coupler. The directional coupler has a first waveguide for receiving the plurality of optical bits in the first wavelengt h, as well as a second waveguide for receiving a continuous wave ("cw") signal in the second wavelength. The directional coupler also includes an output port, as well as a coupling region. In response to an optical bit of the plurality in the first wavelength being a binary one, the cw signal is coupled from the second waveguide to the output port.
