Abstract: PROBLEM TO BE SOLVED: To compensate for Raman effect by producing a gain inclined against Raman inclination in advance and applying the inclined gain to the spectrum of optical signals transmitted through an optical fiber. SOLUTION: A gain inclined against Raman inclination in advance is produced and the inclined gain is applied to the spectrum of optical signals transmitted through an optical fiber. For example, when an optical signal is transmitted from the output of an optical amplifier 100-i, e.g. 100-1, the gain is inclined at the low end of spectrum. Then a receiving optical amplifier, for example, an amplifier 100-2 amplifies a received signal and processes it again so that the power level of the optical signal is preliminarily inclined against Raman inclination produced in a transmitted light transmission line. With this constitution Raman effect can be offset.

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: An optical amplifier is adapted to cancel the Raman gain of an optical transmission path that degrades those optical signals occupying the low end of the bandwidth such that the power is transferred from the latter signals to the optical signals occupying the high end of the bandwidth. More specifically, the optical amplifier adjusts the gain that it applies to the optical signals so that it favors the signal components at the low end of the bandwidth.

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: 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.
