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.
