摘要： A method of establishing a data connection between terminal switching nodes in a network and switching nodes for implementing the method. The method involves switching nodes participating in a network layer wavelength routing (WR) protocol to determine the next hop switching node for every possible combination of terminal nodes based on the network topology. The method also involves the switching nodes participating in a network layer wavelength distribution (ND) once the data connection is to be established. The WR protocol determines the path used through the network, while the WD protocol assigns wavelengths on each link between switching nodes. The wavelengths may be different on different optical links. The switching nodes include wavelength converters with an optical switch or optoelectronic converters with a digital electronic switch. A digital electronic switch can also provide signal reformatting. Advantages of using potentially different wavelengths along various segments of a single end-to-end connection yields increased wavelength efficiency.

摘要： A wavelength converter includes first silicon waveguides and second silicon waveguides intersecting the first silicon waveguides to form an arrayed waveguide. The arrayed waveguide receives optical data signals at the same wavelength at a first input and optical pump signals at different wavelengths at a second input. Microring resonators evanescently couple different ones of the first silicon waveguides to different ones of the second silicon waveguides. Each microring resonator is tuned to the wavelength of the optical data signals or one of the wavelengths of the optical pump signals, so that different combinations of the optical data signals and the optical pump signals are provided at an output of the arrayed waveguide. A non-linear optical media converts the wavelength of each combined optical signal at the output of the arrayed waveguide to yield wavelength converted signals each having a new dedicated wavelength.
