The DPC5500 is an inline deterministic polarization controller that combines deterministic state of polarization control, high speed, low loss and high accuracy in a unique and unprecedented way. This polarization controller is comprised of our high speed, low loss IPM5300 polarimeter technology and a non-deterministic state of polarization (SOP) controller. The DPC5500 is ideal for R&D, manufacturing or industrial applications that require precise deterministic control or locking of a signal's SOP.
It facilitates the SOP control at a user-defined location in the optical system such that the SOP can be varied to accurately and precisely follow a prescribed path on the Poincaré Sphere. Compared to existing systems, the DPC5500 eliminates the inadequacies of most commercially available SOP controllers whose output SOP depends on the input SOP. The DPC5500 also does not suffer from drift and hysteresis effects like most other commercial high speed SOP controllers. The new all-fiber technology of the DPC5500 provides true deterministic control with very low insertion loss.
The desired SOP may either be defined via its azimuth/ellipticity parameters or its corresponding Stokes values which are graphically defined by a point on the Poincaré Sphere. Software modules for electronic SOP control, SOP tracing on the Poincaré Sphere and SOP scrambling are available for specific applications.
SOP Scrambler Feature
This included software package adds a powerful SOP scrambling functionality to the DPC5500 that randomly distributes the SOP of the output over the Poincaré Sphere in controlled and well defined patterns. Please see the SOP Scrambler Tab for details.
Based on Thorlabs' TXP5000 Modular Test & Measurement System, the DPC5500 offers additional features like USB/Ethernet ports, 'plug and play' combination with other modules (see Related Items Tab), an easy-to-use graphical user interface, and flexible configuration via LabVIEW™, Labwindows/CVI™, MSVC and Borland C drivers.
The DPC5500 is a single TXP card and includes the graphical user interface as well as all the drivers for LabVIEW™, Labwindows/CVI™, MSVC and Borland C.
The DPC5500-T is a complete plug-and-play system and includes the TXP5004 Mainframe and a preconfigured laptop computer.
