    Notes: Abstract A simple method for increasing fringe visibility of an interference pattern in a Mach-Zehnder type fibre interferometer is presented. In order to obtain high visibility, two elliptically polarized waves emitted from fibres with birefringence are transformed into two linearly polarized waves of equal amplitude and with parallel planes of polarization by using ordinary optical components. Instability of fringe patterns due to temperature fluctuation of the air surrounding the fibres is also discussed.

    Notes: Abstract This paper presents an accurate method for observing fringe movement in a Mach-Zehnder type fibre interferometer. We place a photodetector in each of two interference patterns formed by a half-mirror and waves emitted from single-mode fibres. By applying the output voltages of the detectors to X- and Y-terminals of an oscilloscope, we can observe the fringe movement as a rotation of a bright spot along a Lissajous figure.
