Phys. Rev. D 63, 062003 (2001) [10 pages]Experimental feasibility of measuring the gravitational redshift of light using dispersion in optical fibersReceived 31 July 2000; published 21 February 2001 This paper describes a new class of experiments that use dispersion in optical fibers to convert the gravitational frequency shift of light into a measurable phase shift or time delay. Two conceptual models are explored. In the first model, long counterpropagating pulses are used in a vertical fiber optic Sagnac interferometer. The second model uses optical solitons in vertically separated fiber optic storage rings. We discuss the feasibility of using such an instrument to make a high precision measurement of the gravitational frequency shift of light. © 2001 The American Physical Society URL:
