CONSTITUTION: The amplifier element 105b and the amplifier element 109b are so disposed that the optimum polarization directions are optically orthogonally intersected. For example, the TE wave with respect to the amplifier element 105b is the TM wave with respect to the amplifier element 109 and the TM wave with respect to the amplifier element 105b is the TE wave with respect to the amplifier element 109b. A specified amplification degree is, therefore, obtd. even if the signal light has the polarization in any direction. The isolators 102, 112 on the input side and the output side prevent the reflection from the outside of this optical amplification system. The hermetic sealing of the amplifier elements is effectively executed in this way. Further, the stable optical coupling is attained.
