|Abstract: ||The concept of nested fibre optic long period grating (LPG) based
interferometers is introduced. A number of in-series, identical LPGs may be used
to form a set of nested, multiplexed Mach-Zehnder interferometers that may
demodulated and demultiplexed by virtue of a Fourier analysis of the optical
spectrum. The concept is demonstrated by the use of three LPGs to form a nested
set of interferometers.|
