LUNA PDD-001 Polarization Diversity Detector

Product Code:

PDD-001

Manufacturer: Luna Technologies

The LUNA 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.

High detection sensitivity
High extinction ratio
Compact

Description

The LUNA 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.

The PDD-001 provides a simple method for monitoring polarization change and the balance between polarization components of a signal.
