Fiber optic polarizer 600-1550NM
Part number fop-11-11-1550-9/125-s-p-50-scasca-1-1
Fiber Optic Polarizers are designed to polarize the output from a
light source or fiber and launch it into an output fiber. These
polarizers typically consist of input and output collimators with a
plate polarizer in between. Broadband polarizers are used, so the
power extinction ratio is maintained for up to several hundreds of
nanometers. The same polarizer, for example, may be used for
1300 nm to 1600 nm. The power extinction ratio is the ratio
between maximum and minimum output power as the input
polarization state is changed. This is different from the output
polarization extinction ratio, which is a measure of the ratio
between the power in the two axes of polarization maintaining
fiber. This value is dependent upon the extinction ratio of the
polarizer, the alignment of the output fiber axes to the polarizer
and the extinction ratio of the output fiber. When an output
extinction ratio is specified, it is the polarization extinction ratio.
This value is only applicable when the output fiber is polarization
maintaining fiber. The power extinction ratio will always equal
exceed the polarization extinction ratio.
