Abstract: An optical packet network system of a ring type, capable of preventing degradation of an optical signal, can be implemented by providing a mechanism relatively simple in structure, capable of erasing light noise if the optical packet signal does not exists. In the optical packet network system made up by interconnecting respective nodes adjacent to each other, and connecting a sending source of an optical packet signal to a ring, a light noise removal function block is provided between the respective nodes adjacent to each other.

Abstract: An optical switch has an input port, output ports, optical waveguides whose output path of an optical signal branch into two. A first stage optical switch section is provided in a branching portion of the optical waveguide, which switches a propagating path of an optical signal to a path leading to the desired output port. A subsequent stage optical switch section is provided in a branching portion of the optical waveguide subsequent to the first stage optical switch section, which switches a propagating path of a leakage light, which is leaked from the first stage optical switch section, to a path which does not propagates the leakage light to any of the output ports. The first stage optical switch section and the subsequent stage optical switch section switch a path of an optical signal according to a refractive index change caused by a carrier injection.
