The A3000 contains a high-speed polarization controller plus 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 as occurring for example through temperature drift and mechanical settling processes. The stabilized output signal is guided in a Polarization Maintaining Fiber (PMF). Alternatively an external electrical feedback signal can be provided for stabilizing the SOP. This signal can be provided either as analogue signal or as RS232 / GPIB data signal.
- 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. The SOP is stable for a predefined time until it again switches to a new SOP. 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 A3000 switches to a set of SOPs which allow PMD / PDL testing of optical components according to the Muller Matrix method or to the Jones-Matrix-Eigenanalysis (JME) method. The JME based measurements are in particular easily performed by using Adaptif Photonics¿ A1000 High Speed Polarization Analyzer as receiving unit (see section ¿Application Examples¿ in this data sheet).
- As traditional Scrambler the A3000 varies the output SOP in a completely random / pseudo random way.
The unit does not contain any moving parts and therefore is robust and withstands even rough environmental conditions. All abovementioned applications of the A3000 are supported by Adaptif Photonics¿ polarizationNAVIGATORTM PC based application software which comes along with this instrument. Instrument drivers compatible with LabView are provided.
