Evaluation of the optical switching characteristics of erbium-doped fibres for the development of a fibre Bragg grating sensor interrogator

Rigas, E.; Correia, Ricardo N.; Stathopoulos, N. A.; Savaidis, S. P.; James, Stephen W.; Bhattacharyya, Debabrata; Kirby, Paul B.; Tatam, Ralph P. (SPIE, 2014-06-02)

A polling topology that employs optical switching based on the properties of erbium-doped fibres (EDFs) is used to interrogate an array of FBGs. The properties of the EDF are investigated in its pumped and un-pumped states ...
Transmission line method for the simulation of Fiber Bragg Gratings

Stathopoulos, N. A.; Savaidis, S. P.; Simos, H.; Rigas, Evangelos; Correia, Ricardo Goncalves; James, Stephen W.; Tatam, Ralph P. (Optical Society of America, 2019-01-04)

A new method for the analysis and design of fiber Bragg gratings (FBGs) based on the theory of transmission lines has been developed and verified both theoretically and experimentally. The method is an extension of the ...
