Helica™ 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 within a fiber. The polarized light is scattered over the length of the chiral grating rather than absorbed.

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. Custom pigtails, jacketing, cabling and connectorization can be accommodated. Please speak to us about your specific needs.

Applications:

  • Polarization measurement and control

  • Coherent transmission

  • Optical sensors

  • Test and measurement instrumentation

  • Navigation instrumentation

  • R & D

  • Fiber lasers

Helica™ In - Fiber Circular Polarizer

Chiral Photonics, Inc. (CPI), introduces an all-glass, in-fiber polarizer based on its proprietary chiral technology that provides a circularly polarized output in a fiber format.

The polarizer can be manufactured to meet your spectral and performance specifications, including central wavelength, bandwidth and extinction ratio requirements. Specifications are shown below.

The circular polarizer acts as a quarter waveplate and the quality of the output circularly polarized light is dependent on the quality of the linearly polarized light that is input into the device.

Pigtailing and connectorization of the device can be customized, as needed. However, an output connector is not recommended. The output SM fiber should be kept as short and unperturbed, mechanically and thermally, as possible. Chiral Photonics has not tested an output fiber that has demonstrated maintenance of good circular polarization extinction ratio (cPER), similar to what exists for linearly polarized light.

Please call us to discuss your specific requirements and receive a prompt quotation.

Applications:

  • Polarization measurement and control

  • Optical sensors

  • Test and measurement instrumentation

  • R & D
