Introduction To Modulator Bias Controllers | PDF | Modulation | Optical Fiber The mbc null controller operates by default at the null point. its fully digital control method enables the controller to quickly lock onto the working point, ensuring the modulator outputs the maximum extinction ratio. The highest extinction ratio depends on and cannot exceed the system modulator maximum extinction ratio. this experiment is conducted by measuring and comparing the power of modulator controlled at peak and null respectively.

Modulator Bias Controller This controller is a continuously tunable bias controller, enabling operation at any point along the intensity modulator's transfer function. this adaptability makes it suitable for a range of telecom modulation schemes, including nrz, dpsk, rz, and more. The modulator bias controller can be used to lock the working point of the modulator at the positive slope quadrature (quad ), negative slope quadrature (quad ), null or peak points of its characteristic curve. the locking modes and slopes are selectable by changing the jumper positions on the pcb. a pigtailed photodetector is included. In this paper, a novel auto bias control technique is proposed, which could realize any operating point control for mz modulator. the output optical power and its deviations are used as feedback signal. The mbc null controller supports serial communication. users can switch the controller’s working mode (automatic/manual), customize the output voltage, adjust the dither signal amplitude, read system working parameters, and set special working points via gui software or by sending standard commands.

Tracking point: peak, null point;typical mbc null applications:* brillouin scattering system and other optical sensors* pulse applications* carrier suppressi. Thanks to the excellent control algorithm design, users can easily lock the modulator at common working points like peak, null, and quad through simple operations, allowing the modulator to maintain good working conditions over extended periods. The purpose of an m z bias controller is to maintain an optical modulator's bias at the quadrature point. along with amplitude control, bias control insures that the extinction ratio is maintained at its maximum level. This function is used together with pause control. when pause control is executed and the automatic control is needed, executing this command will resume automatic control.
