- 13 - ABSTRACT (ref Figure 1) An an all optical fibre interferometer is formed from an optical fibre Mach-Zehnder interferometer (25) whose output ports (18,20) are coupled by an optical fibre loop (20) which relaunches any optical signal output from either of the output ports (18,20) into a respective one of the output ports (20,18). A piezo-electic stretcher 26 is used to adjust the length of the arm (22) relative to the other arm (24) in response to a measurand. The interferometer outputs at port 1 an intereference signal dependant on the relative optical path length of the arms (22,24) allowing a measurand to be monitored via the same port 1 as the input optical signal Iin is coupled. This allows remote sensing via a single optical fibre coupled to port 1. The interferometer also finds application as a reflection modulator as a variable reflectivity mirror and Q-switch for a fibre laser.
