NuCrypt PA-1000 Polarisation Analyser

Featurette

• Calibrated polarisation controller (program independent phase shifts from 0−360˚ on all of the variable waveplates)
• Single or multiple channel systems are available with single (linear polariser) or multiple (PBS) outputs per channel
• PA-1000 has low insertion loss (1 dB) and fast 100 Hz reconfiguration rate

Applications

• Measure polarisation entangled light (basis selection)
• Deterministic polarisation state generation
• Polarisation state scrambling
• Polarisation dependent loss measurements
• Combine with single photon detectors (CPDS) for ultra low-power (-100 dBm CW) polarimetry

Descriptions

The PA-1000 is a computer-controlled fiber coupled polarisation analyser that offers precise and accurate measurements. It is composed of a calibrated polarisation controller, which is followed by either a linear polariser or a polarisation beam splitter. This configuration allows for the selection of the desired basis state when measuring polarisation entangled states of light. The polarisation control is achieved through the use of four or more variable waveplates, each with their optical axes oriented at 45˚ angles with respect to each other. This ensures optimal control and manipulation of the polarisation state.

The versatility of the PA-1000 is evident in its ability to function as a stand-alone device, controlled conveniently via a USB port. However, it also has the capability to be seamlessly integrated with other equipment, such as the NuCrypt CPDS-1000 detection system and NuCrypt Quantum System Control Software. This integration enables the automation of quantum measurements, including two-photon interference (TPI) fringes and quantum state tomographies (QST). By combining these systems, researchers and scientists can conduct advanced experiments and gather valuable data with ease and efficiency.

In summary, the PA-1000 is a sophisticated and adaptable polarisation analyser that provides researchers with the tools they need to accurately measure and manipulate polarisation entangled states of light. Its compatibility with other equipment and software further enhances its capabilities, allowing for automated quantum measurements and expanding the possibilities for quantum research and experimentation.
