PSG-001 Polarization State Generator General Photonics Datasheet

Product information "PSG-001 Polarization State Generator"

1260-1620 nm; IL 1.0, 1.2 dB; WDL ≤0.3 dB; Switching Speed ≤250 µs; Repeatability ±0.1°; RL ≥55 dB

General Photonics’ PSG-001 high-speed polarization state generator (PSG) module generates six states of polarization (-45°, 0°, 45°, 90°, RHC & LHC) across the Poincaré sphere in less than 250 μs, with a repeatability of less than 0.1 degrees.

In addition, PSG-001 comes as a compact module ideal for integration into systems that require precise generation of these six polarization states or precise 90° polarization rotation. The PSG-001 polarization state generator is easily controlled with a 6-bit TTL signal either from a microcontroller or a computer.

PSM-003 Polarization Controller/Scrambler

1260-1650 nm; IL 0.05, 0.1 dB; PDL <0.01, <0.1 dB; PMD <0.05 ps; AL 0.01, 0.1 dB; RL >65 dB General Photonics’ PSM-003 series includes a 3-axis polarization controller (PSM-003-C) and polarization scrambler (PSM-003-S). They use the same patented all-fiber design as the larger General Photonics polarization controllers and therefore have the associated benefits of low insertion loss and minimal back reflection. This OEM micro polarization controller/scrambler integrates General Photonics’ 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. Both versions are packaged in a 2 cubic inch module, require only ±12 VDC power supplies, and their low power consumption enables use in battery-powered handheld devices. Optional measurement grade versions of both modules are available with very low PDL and activation loss. The state of polarization (SOP) of the PSM-003-C micro polarization controller’s output signal can be controlled via three analog 0 to 5 V control voltages. This device is ideal for integration into OCT or sensor systems to maximize signal output. The PSM-003-S micro polarization scrambler can perform either continuous, smooth trace scrambling at a rate of up to 60π rad/s or random scrambling control at a rate of up to 5 discrete points/s. Continuous scrambling versions can be specified with one of 6 scrambling rate options, and random versions with one of four scrambling rate options. Scrambling can be disabled/enabled with a 5 V TTL signal. This module is ideal for integration in a PDL measurement instrument or in a sensor system to minimize polarization related measurement uncertainties.
