Time-Domain Measurements of Reflection Delay in Frustrated Total Internal Reflection

摘要

We present experimental evidence that the contribution of the Goos-Haenchen shift to tunneling delay is suppressed in frustrated total internal reflection. We use a Hong-Ou-Mandel interferometer to perform direct time measurements of reflection delays with femtosecond resolution at optical frequencies, and take advantage of a liquid-crystal-filled double-prism structure to dynamically change the refractive index of the barrier region.
