Response to Comment on “Probing the Ultimate Limit of Fiber-Optic Strain Sensing”

G. Gagliardi; M. Salza; S. Avino; P. Ferraro; P. De Natale

<jats:p>Cranch and Foster argue that the strain resolution of our fiber resonator sensor is not limited by thermal noise. However, extension of common theoretical models to high-finesse passive resonators at low frequency needs further attention. Our findings are consistent with noise of thermodynamic nature for which no experimental evidence in the infrasonic range was available until recently.</jats:p>

Comment on “Probing the Ultimate Limit of Fiber-Optic Strain Sensing”

Geoffrey A. Cranch; Scott Foster

<jats:p> Gagliardi <jats:italic>et al</jats:italic> . (Reports, 19 November 2010, p. 1081) described an ultrahigh-resolution fiber-optic strain sensor. This comment addresses an error in the calculation of the fundamental thermodynamic noise in optical fiber resonators and shows that the actual thermodynamic noise level is lower by a factor of at least 11 than that calculated. </jats:p>
