zing polarizingfiber
FibercoreZing™ is an all-fiber polarizer, guiding only a single-polarization state,providing practical real-world polarizing performance. Straight or coiled,Zing™ delivers the high Polarization Extinction Ratio (PER) and broad, stableoperating window that applications demand.
The secret of this extremeperformance, is the extreme birefringence that only a ‘Bow-Tie’ geometryPolarization Maintaining (PM) fiber can create. With polarization beat-lengthsapproaching 0.5mm at 633nm, Fibercore Zing™ can provide 100nm of practical,usable polarizing bandwidth, providing a wide variety of packaging and sourceoptions – cabled or coiled, narrow line width laser or broadband AmplifiedSpontaneous Emission (ASE) source.
The polarizing window may be tunedby changing the length of the fiber and the coil diameter, either individuallyor together, altering the central wavelength and the width of the operatingwindow.
Advantages:
• Broadband polarization window
• High polarization extinction ratio
• High stability over temperature and vibration
