In-Line Fiber Polarizer

Rainbow Bar

Chiral Photonics, Inc. (CPI), introduces a unique in-fiber polarizer based on its proprietary chiral technology. CPIs all-glass In-Fiber Polarizer provides a high extinction ratio over a broad spectral range at a price well below other in-line polarizers.

The polarizer can be manufactured to meet your spectral and performance specifications, including central wavelength, bandwidth and extinction ratio requirements. Specifications for a polarizer with central wavelength at 1550 nm are shown, as an example, below.

Harsh environment requirements can also be accommodated, including chemical, temperature and radiation resistance. Highly stable operating performance above 200 C has been demonstrated. A wide variety of input and output fibers as well as connectors are available to meet your needs. Please call Metrotek to discuss your specific requirements and receive a prompt quotation.

Theory of operation:

The above schematic offers insight into the operation of the In-Fiber Linear Polarizer. Incoming vertically polarized light is converted into an elliptically polarized component of the same handedness as the chiral structure while being scattered out of the fiber. In contrast, horizontally polarized light is converted into elliptically polarized light of opposite handedness and back to horizontal polarization and is freely transmitted by the structure.
