Paper Abstract

An all fiber Fabry-Perot interferometer is proposed, using coherence demultiplexing and fiber loop reflectors, whereby the inherent disadvantages of the interferometer can be overcome. Disadvantages include the limited sensing range and the non-linear output. The limited sensing range is overcome by the use of coherence demultiplexing and the bilinear transform is used for linearizing the output. Coherence demultiplexing is achieved using a double cavity Fabry- Perot interferometer consisting of two cavities formed between the three fiber loop reflectors. An added advantage using two cavities, is the ability to introduce a phase generated carrier demodulation system.
