    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: In the measurements of optical characteristics, such as measurements of group delay using an interferometric system, vibration noise can be at least partially offset by providing corrections on the basis of detecting light patterns that are indicative of the vibration noise. In each embodiment, light beams propagating through first and second paths are combined to form an interference signal, which is analyzed to provide the basis for the adjustments.
