POLARISATION DIVERSITY ASSESSMENT FOR THE USE OF A POLARISATION MULTIPLEXIED TRANSLATION SOCIAL ATTOR

摘要

Determining properties of an optical device under test (ODUT), includes: splitting an incoming light beam into first and second light beams, coupling the first light beam into the ODUT, letting the second light beam travel a different path as the first light beam, splitting the second light beam into first and second parts, delaying the second part of the second light beam relative to the first part of the second light beam, recombining the first and the second parts of the second light beam, superimposing the first light beam and the recombined second light beam to produce interferences between the first light beam and the recombined second light beam in at least one resulting superimposed light beam as a function of frequency and polarization when tuning the frequency of the incoming light beam over a given range, deriving the optical property of the ODUT from the frequency dependence of the detected powers.
