| Abstract: | The input polarization angle directly affects the performance of semiconductor optical amplification link. The powers and noises in spontaneous emission noise limited system are analyzed, the expression of signal noisc ratio and system BER is further deduced. The results show that the use of polarimeter arid automatic temperature control circuit is helpful to the improvement in such communication links. |
