In-fiber linear polarizer
Chiral Photonics, Inc. (CPI), introduces a unique
in-fiber polarizer based on its proprietary chiral technology.
CPI’s 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.
Applications:

Chiral Long Period Gratings
Chiral Photonics, Inc. (CPI), has developed
unique long period gratings based on its proprietary chiral
technology. Chiral long period gratings (CLPGs) can be used
to optically sense environmental factors, such as chemical
composition, temperature, and pressure. Unlike conventional
long period gratings, CLPGs are sensitive to circularly polarized
light with the same handedness as the chiral fiber. Light
that is oppositely polarized can be used for control purposes,
to assure the system’s integrity, or to serve as a second
sensing channel. Since chiral fiber gratings are not formed
in photosensitive fibers, they can be fabricated from refractory
or radiation resistive glasses. CLPG sensors can therefore
be used to probe harsh environments with high levels of radiation,
high temperature, or corrosive chemicals such as might exist
in nuclear power plants or in bore holes in oil fields and
in deep mines.
A wide variety of sensors as well as input and output fibers
are available to meet your needs. Below is a spectrum showing
the sensitivity of a CLPG to its environment. These fibers
have demonstrated their advantages in fuel level sensing,
pressure and temperature measurement. The wavelength of the
dip can be tailored to suit the application.
Applications:
> Environmental sensing
> Strain / pressure sensing
> Temperature sensing
> Fuel level sensing
> R&D
