Hoekstra author Manfred Hammer author 480770000-0002-6331-9348 61 department The relevance of our definition for sensitivity in refractometric sensing, being the relative change in the transmittance of a certain output channel of an optical device over the change in the refractive index of the probed material, is discussed. It is compared to one based on spectral shift per refractive index unit change. Further, there is discussion on how group delay and sensitivity are interrelated and can be converted into each other and which physical quantities are relevant for high sensitivity. As a by-product of the theory presented, a general expression relating group delay and the ratio of the time-averaged optical energy and the input power is presented. https://ris.uni-paderborn.de/download/3937/3938/2014_07_Hoekstra,Hammer_General relation for group delay and the relevance of group delay for refractometric sensing_OSA.pdf application/pdf The Optical Society2014 eng tet_topic_waveguide 0740-3224 1520-854010.1364/josab.31.001561 317 Hoekstra, H.
