Gestion de la polarisation


General Photonics phase shifter produces phase shifts up to 15 pi at modulation frequencies from DC to 20 kHz.
The VDL-002 is a miniaturized variable optical delay line designed specifically for OEM applications. With a delay range of up to 250 ps, this device is a superior replacement for the variable RF phase shifters inadequately adapted from the RF/wireless field for fiber optic communications.
The PolaStay polarization tracker automatically adjusts the state of polarization (SOP) towards a reference SOP, counteracting continuous input SOP variations as fast as 0.9 ms with no resets.
GPC´s Scrambler module uses a breakthrough all- fiber technology to effectively randomize polarization states. This module is designed to be easily plugged into sensor equipment or measurement instruments with minimal development effort.
GPCs´ 4-axis Polarization Scrambler Module uses a breakthrough all-fiber technology to effectively randomize polarization states. Depolarizing by polarization scrambling has many important applications:
GPCs´ miniature polarization scrambler module, the PSM-002, is specially designed for integration into sensor and communication systems that need to work in extreme environmental conditions.
This OEM micro polarization controller integrates GPCs all-fiber dynamic polarization control technology with miniature electronic drive/control circuitry into a compact, self-contained device that provides full polarization control functionality while minimizing volume, power consumption, and cost.

GPCs´ in-line polarimeter is specially designed for low cost, high-speed polarization characterization without interrupting data traffic. It outputs four voltage signals for calculating both the degree of polarization (DOP) and the state of polarization (SOP) of the light passing through the device in microseconds.
GPCs´ high-speed polarization state generator (PSG) module provides the ability to generate 6 states of polarization (-45°, 0°, 45°, 90°, RHC & LHC) across the Poincaré Sphere in less than 250 ?s, with an impressive repeatability of less than 0.1 degrees.
This module integrates a General Photonics all-fiber dynamic polarization controller with miniature piezo driver card, so that the SOP of the signal can be directly controlled either by a 0-5V analog control signal or a 12-bit TTL digital control signal. Because there is an on-board HV DC/DC converter, no external high voltage power supply is required.
Speckle patterns from a multimode fiber can cause problems in many applications that require uniform, stable light distributions at the fiber output. The MMS-201 multimode scrambler, is specially designed to solve this problem.
