摘要： A new method for characterising the amplitude and phase distributions of the light propagating through arrayed-waveguide gratings is presented. The new method is based on the IFT. A very good agreement of the results obtained from the IFT method in comparison with OLC method has been achieved. The new method has been applied to an AWG with a small ΔL of 22 µm where the other methods fail. The precision of this measurement is demonstrated by a good agreement between the transmittance obtained from direct measurement and from calculation using the amplitude and phase distributions. Finally we want to point out, that although the results are based on a FTS measurement, the method can be applied to any experimental technique that provides a measurement of the complex transmittance of the AWG.

The optical component of the test structure may be connected by optical fibers or integrated into a single substrate.

摘要： An interferometer apparatus for an optical fiber system and method of use is described. The interferometer comprises an optical coupler and optical fibers which define first and second optical paths. Light propagating in the first and second optical paths is reflected back to the optical coupler to generate an interference signal. First, second and third interference signal components are directed towards respective first, second and third photodetectors. The third photodetector is connected to the coupler via a non-reciprocal optical device and is configured to measure the intensity of the third interference signal component directed back towards the input fiber. Methods of use in applications to monitoring acoustic perturbations and a calibration method are described.
