Fiber Optics


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.
GPCs alle Festkörperpolarisationsschalter können die SOP des einfallenden Lichts schnell und wiederholbar um einen festen Winkel, entweder 45 oder 90 Grad, drehen. Sowohl Single-Mode- als auch PM-Faser-Pigtailed-Versionen sind verfügbar.
This is the in-line version of the PolaRITE polarization controller. It can be inserted into a fiber optic system to control the polarization state of light without having to disconnect any part of the system.
The MPC-203 is a special version of GPCs’ Multifunction Polarization Controller which can reach extremely high rates of polarization change. It combines PolaRite™ II/III polarization controller with proprietary polarization control algorithms to achieve a wide range of polarization control functionalities.

GPC-FST-001

The FST-001-B is a piezo-driven fiber stretcher with a long optical delay range of up to 3 mm. The device comes complete with a piezo driver packaged in a user-friendly small enclosure.

GPC-FPS-002

GPCs’ 2nd generation all fiber phase shifter/modulator provides phase shifts up to 65π with a much lower half-wave voltage (~2 volts as compared with 10-20 volts for the 1st generation phase shifter) at frequencies from DC to 20 kHz

GPC-FPS-003

The FPS-003 all fiber phase shifter/modulator combines a wide modulation bandwidth (up to 60 kHz) with low half-wave voltages to create a long-range device that can be driven by standard function generators.
OCT and sensor systems require high performance balanced photodetectors to increase system signal to noise ratio. Polarization sensitive OCT and similar applications require separate analysis of the two polarization components of a signal. The PBPD-001 is specially designed for use in such systems.
Simultaneously detecting the powers of two orthogonal polarization components is important for many sensor and measurement applications. A pigtailed polarization beam splitter coupled with two photodetectors can be used for such applications; however, this arrangement is bulky, troublesome to handle, and costly.
Simultaneously detecting the powers of two orthogonal polarization components is important for many sensor and measurement systems, to either obtain polarization related information or minimize polarization sensitivity.
