Polarization Diversity Detector
The PDD-001 Polarization Diversity Detector combines a high ER polarization beam splitter with matched photodetectors to simultaneously monitor the powers of both polarization components of a signal.
The PDD-001 integrates polarization-splitting components with photodetectors in a compact, durable package that can easily be mounted onto a circuit board. It provides real-time monitoring of polarization changes with high detection sensitivity, high extinction ratio, high reliability, and small size.
