Document Type and Number:
Japanese Patent JP4158655
Kind Code:

Abstract:
A first semiconductor optical amplifier is disposed on a first arm of a Mach-Zehnder interferometer and a second semiconductor optical amplifier is disposed on a second arm. An optical splitter splits a probe light into two portions and applies one portion to the first arm and the other to the second arm. A first optical coupler combines the probe lights output from the first and second arms. A second optical splitter splits a data light into two portions. A second optical coupler applies one output from the second optical splitter to the first arm in the backward direction. A third optical coupler applies the other output from the second optical splitter to the second arm in the forward direction.
