Sammut %K intensity modulation %K coupled mode theory %K mode coupling %K transmitted light %K curved optical fibres %X Coupled-mode theory is used to explain the intensity modulation of transmitted light which results from small changes in the radius of curvature. It is shown that the mode coupling induced by bends in small-V fibres introduces an uncertainty into light-transmission measurements. %@ 0013-5194 %T Intensity modulation of light transmitted in curved optical fibres %B Electronics Letters %D September 1977 %V 13 %N 18 %P 545-546 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=13nq4x1kbhla5.x-iet-live-01content/journals/10.1049/el_19770392 %G EN
