The GracyFiber PM Fiber Polarizer is an in-line polarization component intended for optical systems in which a controlled linear polarization state is required. Its 1×1 configuration provides a direct fiber input-to-output optical path while suppressing the unwanted polarization component and transmitting the desired polarization state.
The product family covers a broad range of photonics wavelengths, from 780 nm through 1950 nm. Different optical and fiber configurations are therefore used according to wavelength. For example, the supplied specification identifies PM780-HP output fiber for the 780/850 nm group, PM980 for 980/1064 nm, PM1300 for 1310 nm, PM1550 for 1480/1550 nm, and PM1950 for the 1950 nm version.
Optical performance also varies by wavelength. The lowest documented typical insertion loss is 0.3 dB for the 1310–1550 nm configurations, while the typical extinction ratio reaches 30 dB for the 980/1064 nm and 1310–1550 nm wavelength groups. These values align with the product description's emphasis on low loss and high polarization purity.
The component can be supplied in different mechanical formats depending on integration requirements. Bare-fiber and 900 µm versions use compact cylindrical packages, while 2 mm and 3 mm tube configurations use larger protective housings.
Connectorized configurations are also supported. Because connectors affect insertion loss, return loss, and extinction ratio, the supplied specification provides separate adjustment values for connectorized versions.
These characteristics make the PM Fiber Polarizer applicable to laser systems, coherent communication, quantum optics, sensing, interferometry, and laboratory optical platforms where polarization purity is an important system parameter.
Fiber laser systems may require a defined linear polarization state within the optical path.
The PM Fiber Polarizer can be inserted into the fiber system to suppress the unwanted polarization component and provide a polarization-controlled output. Multiple wavelength options, including 980 nm, 1064 nm, 1550 nm, and 1950 nm, allow the configuration to be selected according to the laser system.
Fiber laser systems are specifically listed as a target application.
Quantum optical platforms can depend on stable and controlled polarization states for optical experiments and signal processing.
The PM Fiber Polarizer provides an in-line method of obtaining defined linear polarization while supporting wavelengths down to 780 nm in the supplied product family.
Coherent optical and interferometric systems may be sensitive to changes in polarization state.
The PM Fiber Polarizer can provide polarization cleanup within the optical path, with documented low insertion loss and high extinction characteristics for relevant wavelength configurations.
Coherent communication, interferometry, and precision measurement are explicitly listed in the product documentation.
GracyFiber provides passive optical components for polarization-sensitive, wavelength-management, optical communication, and photonics applications.
Relevant product capabilities include:
For this PM Fiber Polarizer family, the supplied specification provides multiple wavelength configurations, wavelength-matched PM fibers, power-handling options, fiber-protection formats, package types, and connector configurations.
