HelicaTM In-Fiber Linear Polarizer

The Helica� In-Fiber Polarizer (IFP) is an all-glass, flexible polarizer for users requiring the best polarization extinction ratio (PER) available over a broad spectral range. The polarized light is scattered rather than absorbed, making this polarizer uniquely suitable for high power applications. IFPs are available as patch cables with either FC/UPC, FC/APC, LC/UPC or LC/APC connectors.

Polarizers have been delivered to address specific spectral needs ranging from 800-2000 nm. Specifications and typical spectra for polarizers with central wavelengths at 1550, 1310, 1064 and 980 nm are shown below.
