The fiber core is an all-fiber polarizer that guides only a single polarization state, providing practical real-world polarization performance. Straight or curly, ZINs offer high polarization extinction ratios (PER) and a wide, stable operating window for application demands.

The secret to this extreme performance is the extreme birefringence that only a "bow-tie" geometry polarization-maintaining (PM) fiber can produce. With a polarization beat length of nearly 0.5mm at 63nm, fiber cores can provide a practical, usable polarization bandwidth of 100nm, offering a variety of package and source options - wired or coiled, narrow linewidth lasers, or broadband amplified spontaneous emission ( ASE) source.

The polarization window can be tuned by changing the fiber length and coil diameter, either individually or together, by changing the central wavelength and the width of the operating window.

1. Broadband polarization window
