Polarisation Extinction Ratio

Polarisation Extinction

The polarisation extinction ratio compares the intensity of light in a fiber with polarisation along the fast axis of the fiber compared to that with polarisation along the slow axis. This measurement is important for any type of qualification of polarisation maintaining components. The requisite light sources and extinction ratio meters needed to perform this type of measurement at various wavelengths are available from AMS Technologies.
