The Keysight 8169A provides determinate SOP setting an internal polarizer and zero-order waveplates from polarized or unpolarized sources with good SOP stability vs. wavelength. Used with N4150A PFL software for Mueller Matrix PDL measurements.
The 8169A Polarization Controller with single-mode fiber input and output is used to change light from any polarized or unpolarized light source into any well-defined state of polarization. The design based on bulk-optic zero-order waveplates and a high-performance linear polarizer at the input provides optimum determination and repeatability of polarization states over a wide wavelength range. The 8169A is especially well suited for use together with a tunable laser to make swept-wavelength measurements of the polarization dependence of fiberoptic devices by setting a set of relatively orthogonal polarization states for Mueller Matrix analysis. These measurements are supported by a Plug&Play driver and coordinated operation of the 8169A with a Keysight tunable laser and power meters can be enhanced with the Photonic Foundations Library software package. The fundamental basis of this flexible instrument also supports many general applications requiring polarization control and analysis. Benefits: Built-in algorithms for controlled polarization scanning Flexible attachment with interchangeable Keysight connector adapters Highly accurate and repeatable output polarization reduces test setup and calibration time and minimizes test uncertainties The low wavel ength dependent movement of the output polarization state empowers high speed swept-wavelength measurements and enables broadband applications.
