    Abstract: PROBLEM TO BE SOLVED: To provide an optical IP router that provides an increased number of input and output channels and provides a higher overall throughput. SOLUTION: This invention discloses the optical router (10) having at least one frequency router (20). The frequency router includes input ports (22, 24) and output ports (26, 28). At least the one input port simultaneously receives at least two optical signals whose frequency paths are to be selected, and at least the one output port simultaneously provides at least two optical signals whose frequency paths are selected. Each optical signal whose frequency path is to be selected is colored in accordance with the destination information.

    Abstract: A compact waveguide grating router is constructed by forming at least first and second free space regions, first and second sets of optical ports, and a gra ting array, onto a substrate.. The grating array is coupled to the first free space region an d the second free space region. A first plane defining a first reflective surface is intr oduced into the first free space region, and a second plane defining a second reflective sur face is introduced into the second free space region. The first plane is oriented su ch that incident optical signals from the first set of optical ports are reflected t o the grating array, and the second plane is oriented such that incident optical signals f rom the grating array are reflected to the second set of optical ports. The first and second planes are provided, for example, by cleaving, cutting, etching, sawing, or any other s uitable technique. The first and second planes enable the input and output ports to be folded back into previously unoccupied space. The aforementioned techniques enable the size of any conventional waveguide grating router to be substantially reduced.

    Abstract: An optical router is disclosed having at least one frequency router. The frequency router includes a plurality of input ports and a plurality of output ports. At least one input port simultaneously receives at least two optical signals to be frequency routed, while at least one output port simultaneously presents at least two frequency routed optical signals. Each optical signal to be frequency routed is colored in response to destination information.

    Abstract: In a system and method of optical communication, optical signals are generated in multiple wavelength channels. Each optical signal is passively transported from an origination node of a network to a destination node. The destination node is determined by the signal wavelength. For at least some signals, the passive transport includes transport through a branch point of the network, such that the signal wavelenth determines the output branch through which the signal is routed. In certain embodiments, signals are generated according to a schedule devised to substantially prevent the concurrent arrival, at the same destination node, of signals having the same wavelength but coming from different origination nodes.
