Bow-Tie Polarization Maintaining Fiber

The core is flanked by areas of high expansion, boron-doped glass, which shrink back more than the surrounding silica. Tension caused induces birefringence (creating two different indices of refraction: a higher index parallel and a lower index perpendicular to the applied stress).

High Birefringence

"Bow-Tie" cladding preserves polarization with stress-induced intrinsic birefringence. The fast axis is oriented horizontally.

Large Wavelength Range and Short Beat Lengths

These Bow-tie polarization maintaining fibers, also known as highly birefringent (HiBi) fibers, are optimized for Visible through NIR wavelengths and have a beat-length of less than 2 mm. The beat-length, the length over which the fiber polarization rotates through 360°, is one of the fundamental performance measures: the shorter the beat-length, the better the polarization-preserving properties of the fiber.

Corning's PANDA Polarization Maintaining Fiber

Corning's PANDA polarization maintaining fibers offer low attenuation and excellent birefringence for high performance applications. Their design uses two stress applying parts to create an extremely high birefringence, resulting in fiber with excellent polarization maintaining properties. The operating wavelengths range from 480 to 1550 nm with beat lengths ranging from less than 1.7 to 5 mm.

Standard and Custom Patch Cables

Standard patch cables are available in several standard lengths with FC/UPC or FC/APC connectors. Please note that slow axis is accurately aligned to the connector key. If you need custom configuration, please use our custom patch configurator model:

Applications

Note on Fiber Length Availability

Due to increasing supply constraints, obtaining fiber lengths greater than 1 km has become more challenging. If you require fiber longer than 1 km, please contact us directly to discuss availability and lead times.
