製品概要 ：

Mach Zehnder structures enable efficient modulation of electrical data signals onto optical carriers but require accurate control of the phase delay set point (DC BIAS) to achieve optimal results. DC BIAS voltages typically drift over time and temperature so that continuous optimization during operation is required.

For Dual Polarization IQ transmitters, this task becomes particularly tedious since nested structures of 6 Mach-Zehnders are required to modulate a single output carrier. Therefore, adjusting 6 interdependent DC BIAS voltages based on a single feedback signal requires a lot of experience and knowledge.

The ID Photonics Automatic Bias Controller (ABC) is designed to automatically find and lock the operating point of Mach-Zehnder modulators to ensure stable optimal performance over time and environmental conditions by a click of a button. By using our controller, you have one thing less to worry about so that you can focus on generating optimal results instead wasting time to tweak BIAS voltages.
