METHOD FOR MEASURING POLARIZATION DEPENDENT LOSS AND INSERTION LOSS

摘要

This invention provides a method of obtaining accurate measurements of polarization dependent loss and insertion loss during the tests aiming at measuring the polarization properties of optical components. This is achieved by taking; into account every polarization disturbance in the line between generation of known states of polarization a nd the device under test. The method involves computing within a desired range of wavelengths either the transfer matrix of each polarization perturbing element or or all polarizati on perturbing elements as a whole, and compensating for errors introduced by these polarization perturbing elements.
