Automatic BIAS Controller

Automatic BIAS Controller


The ID Photonics automatic bias controller (ABC) is designed to lock the operating point of Mach-Zehnder modulators to ensure stable optimal performance over time and environmental conditions.

It covers a wide variety of applications from single polarization Intensity Modulators to polarization multiplexed IQ Modulators by simple user reconfiguration in software.

For IQ modulators, this unique design provides a stable tracking of optimal operating point for arbitrary RF input signals such as QPSK, QAM-xx or Nyquist shaped signals without requiring manual tweaking of parameters. This enables stable operation especially when switching between modulation formats.

A zero noise feature allows achieving optimal and repeatable performance.

A GUI is provided for instant access and a SCPI style command set provides extensive control status information and configurations such as locking status.
