摘要： A system for characterizing optical properties of a device under test (DUT) uses an expanded local oscillator signal to perform multiple parallel interferometric measurements. In one system, the expanded local oscillator signal is optically connected to a lens array. The lens array focuses the expanded swept local oscillator signal into multiple beams. The multiple beams are then used in multiple parallel interferometric measurements. The multiple beams may be used as the reference beams or applied to the DUT and used as the test beams depending on the application. The test beams and reference beams are combined to perform the interferometric measurements. In another system, a portion of the expanded local oscillator signal is applied directly to a DUT as the test beam while another portion of the expanded local oscillator signal is used for the reference beam.

摘要： A heterodyne optical network analyzer and method for device characterization reduces the effect of relative intensity noise (RIN) in interferometric optical measurements by subtracting the measured intensities of first and second interference signals derived from an optical interferometer. The first and second interference signals are produced by combining a first lightwave transmitted to an optical device being characterized with a second lightwave, which is a delayed version of the first lightwave. The first and second lightwaves are derived by splitting an input lightwave having a continuously swept optical frequency generated by a light source, such as a continuously tunable laser.

摘要： By making combined interferometric and polarimetric measurements on a device under test, the relative phase uncertainty in device characterizations performed with a polarimeter or polarization analyzer alone is removed. This allows determination of the group delay to within a constant offset and the chromatic dispersion of the device under test.

摘要： Characterizing active and passive properties of an optical device involves applying a local oscillator signal to a device under test (DUT) and providing a portion of the local oscillator signal (referred to as the reference local oscillator signal) directly to the an optical analyzer. Providing the reference local oscillator signal to the optical analyzer enables interferometric measurements associated with the DUT to be obtained along with direct measurements, where the interferometric measurements result from combining the portion of the local oscillator signal that is applied to the DUT with the reference local oscillator signal. The interferometric measurements are used to characterize passive properties of the DUT while the direct measurements are used to characterize active properties of the DUT.
