Abstract(in English) | Electronic pre-compensation at the transmitter side for equalizing chromatic dispersion in optical fiber transmission systems has been rigorously investigated. In the pre-compensator, an optical I/Q modulator is usually used to generate an arbitrary complex electric field. However, this conventional structure has a problem with unwanted excess loss. We have proposed a novel electronic pre-compensator with coordinate transformation. The excess loss of the dual parallel MZM was improved by up to 3dB thanks to the π/4 axis rotation in the transformation. We also show the tolerance to bias error of the modulator. The numerical results show that the proposed method is effective in diminishing the insertion loss of the modulator. |
