OVERVIEW

Dither-less Automated Modulator Bias Controller

Unlike classical dither signal based bias controllers, the MBC-AN-LAB does not superimpose any tone (dither) signal to the optical modulated wave. It is designed for applications where such a tone signal is not desired, typically for analog applications requiring a high purity carrier. The MBC-AN-LAB is easy to implement, fully automated with its autoset function, and comes in a compact and smart package.

OVERVIEW

It is well known that the inherent drift of Mach-Zehnder modulators is caused by aging and environmental variations. When the modulator is used for optical pulse generation (Min bias point operation), this drift can lead to significant losses in optical pulse extinction ratio.

The iXblue MBC-DG-LAB Modulator Bias Controller (MBC) is designed to compensate for this drift and maintain exceptional accuracy in the modulator bias point, ensuring a high optical pulse contrast and stability.

The MBC-DG-LAB is an automatic bias controller specifically designed to lock the operating point of LiNbO3 Mach-Zehnder modulators, ensuring stable operation over time and under varying environmental conditions. It features an Auto-set function for Min modes, simplifying its use.
