Demonstrated is a microfibre Mach-Zehnder interferometer (MZI) structure which is capable of sensing current changes from 0A up to 2.5A with constant fixed wavelength shift, in linear increment pattern. The fine thin copper wire of 0.16mm radii, 60mm length used to carry electrical current is touche...
