摘要： A technology to automatically control the biasing of an optical duobinary transmitter using a single-drive LN-MZ modulator is provided. A low-frequency signal is amplitude modulated onto a voltage signal input into a Mach-Zehnder optical modulator 22. The optical output from the optical modulator 22 is detected by an optical detection subsystem 30. In a bias control subsystem 40, the low-frequency signal component amplitude modulated onto the electrical signal is detected from the optical output, and a DC bias voltage applied to the optical modulator is controlled such that the low-frequency signal component is either minimized or maximized.

摘要： In the application of the optical transmitter to any system for the compensation of passing degradation, the invention provides the optical transmitter which maintains constant modulator output and the highly reliable optical transmission by tuning, the alpha parameter for given systems.As the optical element back-face output power detected by PD6 depends on the optical element driving current amount, the electronic absorption amount of the EA optical modulator monitored by the electronic absorption monitor depends on the optical output of the optical element 5 and the EA optical modulator driving point of the driving part 8. It is possible to detect a change in the driving point in the EA optical modulator by taking a difference between the amount monitored by the PD 6 and the amount monitored by the electronic absorption monitor. Consequently by applying to the driving current source 10 the current corresponding to the change of the EA optical modulator driving point, it is possible to automatically compensate the modulator output 7 when the driving point of the EA optical modulator changes due to the change of the alpha parameter and the passing degradation.
