LUNA PSW-003/PSW-003-M High-Speed Polarization Switch
The LUNA all solid-state, high speed self-latching polarization switch can quickly and repeatedly rotate the SOP of incoming light by a fixed angle, either 45 or 90 degrees, or convert an input linear polarization state to an output circular polarization state with 45 μs switching time, typically.
- Digitally switched SOP
- Fast switching time 45 μs (typical)
- SOP repeatability 0.1°
- Self-latching
- Zero static power dissipation
- Compact
- Minimal heat generation
The LUNA all solid-state, high speed self-latching polarization switch can quickly and repeatably rotate the SOP of incoming light by a fixed angle, either 45 or 90 degrees, or convert an input linear polarization state to an output circular polarization state. Both single mode and PM fiber pigtailed versions are available. With the PM option, the device functions as a TE to TM converter. Configuring the PM option with an input polarizer improves the PER of the axis-aligned output states.
The PSW-003 is electrically controlled with no moving parts, providing stable long-term performance, with good reliability and repeatability to meet the highly demanding requirements of field applications.
The PSW-003 is a small module suitable for OEM integration wherever polarization switching is required. Applications include polarization diversified detectors and sensors, polarization sensitive OCT, polarization metrology, polarization sensitive OTDR and OFDR, and PMD monitoring.
