PSG-002
High-Speed Polarization State Generator


Luna Innovations’ high-speed polarization state generator (PSG) module enables quick generation of up to six distinctive polarization states (LCP, RCP, Linear ±22.5°, Linear ±67.5° ) across a Poincaré sphere in less than 50 μs between two consecutive states, with high repeatability of less than 0.1 degrees.

The new compact packaging is ideal for integration into systems that require precise generation of these 6 polarization states or precise 90° polarization rotation. The PSG-002 uses a new self-latching technique which reduces power consumption and heat generation.
In addition, its predictable wavelength and temperature dependence allows for easy calibration, making it a perfect choice in swept wavelength component measurement systems.
Other applications include Mueller matrix-based measurements, polarization OTDR, performance monitoring, medical imaging, material birefringence measurements, and fiber sensors.
