Bias Controller Specialist

Make your experiment plug and play

Solutions

We focus on developing optical modulator bias controllers and customized modules. We have patented bias controllers specially designed for LiNbO3 MZ, QPSK, DP-QPSK modulators. We also provide customization services for TFLN bias controllers and EO modulation modules. All of our bias controller products are small in size and easy to use without manual calibration.

Stable within 30 seconds of powering on and maintain precise and stable locking for extended period.

Experiments Diagrams

QPSK Diagram
Under continuous tracking by the controller for tens of hours, the QPSK modulation system consistently maintains excellent performance.

QPSK Diagram

16QAM Constellation Diagram
The control supports xQAM coherent modulation in multiple formats.

Pulse Diagram
Achieving excellent pulse modulation performance with a high extinction ratio modulator.

Pulse Diagram

SSB Diagram
Under the precise control of the controller, the SSB modulation system achieves a measured carrier suppression ratio of 30+dB and a sideband suppression ratio of 40+dB.

SSB Diagram

Carrier Suppression Diagram
Dual sideband modulation is easily achieved with outstanding carrier suppression performance. System's overall effect is close to the performance limit of EOM.

Carrier Suppression Diagram

NRZ Modulation
Under precise working point locking, high-frequency NRZ or PRBS modulation can be achieved, and clear eye diagrams can be easily obtained.
