Optical characteristic measurement system

摘要

An optical characteristic measurement system which can measure optical characteristics of an optical device precisely and stably without being affected by the polarization-dependent loss of optical components in the optical characteristic measurement system. The optical characteristic measurement system includes a multi-wave optical source for generating a signal light of linear polarization having a plurality of wavelengths each different from each other, a polarization scrambler for scrambling the polarization direction of the signal light to be supplied to a device under test, and an average power measurement unit for measuring an average power of the signal light outputted from the device under test, for each of the wavelengths.
