The A3300 contains a high-speed Lithium-Niobate based polarization controller and a polarization analyzer plus a microcontroller based driving circuitry. This unit can operate in various modes:
  • As Polarization Stabilizer it provides a stable output State of Polarization (SOP) even with fluctuations and drifts of the input SOP. The stabilized output signal is guided in a Standard Single-Mode Fiber (SMF). The output SOP can be defined in following ways:
    • Set-and-forget: When the front button is pushed, the current SOP is stored and maintained, even if polarization changes occur on the instrument input.
    • Defined Stokes: The target output SOP can be defined by the user using the Stokes parameters.
  • As Synchronous Scrambler the device switches the SOP of the output signal in a (pseudo) random way. Switching of the SOP occurs within few microseconds. During every switching operation the unit provides an electrical (TTL) trigger signal which allows synchronization of external processes. Alternatively an electrical trigger input can be used to synchronize the scrambler with external events.
  • As SOP Switch the A3300 cycles through a sequence of SOPs with a speed of up to 40 kHz, which corresponds to a cycle time of less than 25 microseconds. The sequence of SOPs can easily be defined by the user using Stokes coefficients.
  • As traditional Scrambler the A3300 varies the output SOP in a random way. Full coverage of the Poincaré Sphere is achieved within few ms.
  • As Polarization Analyzer the instrument provides truly high-speed capabilities: More than 500 000 samples can be taken with a sample rate of up to 1 Megasample per second.

The unit does not contain any moving parts and therefore is robust and withstands even rough environmental conditions. All abovementioned applications of the A3300 are supported by Adaptif Photonicsâ polarizationNAVIGATOR PC based application software which comes along with this instrument. Instrument drivers compatible with LabVIEW® are provided. Connectivity to external applications (LabVIEW®, Excel, ERP Database, etc.) are provided through a DLL interface. Examples are provided in LabVIEW® and Excel.
