PSG-002 Polarization State Generator
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°.

Product Description

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 and other applications.
