Automated bias control for IQ-Mach Zehnder structures unveiled by ID Photonics
Test and measurement technology developer ID Photonics now offers what it describes as a new type of automatic bias control for complex multi-level signals such as 16QAM. The control offering, jointly developed with Fraunhofer Heinrich-Hertz-Institute, is independent of the applied RF signal (constellation), requires no manual tuning, and features a zero noise mode for reference measurements, according to the company.
