Unruh effect in a waveguide
arXiv:physics/0606072 · doi:10.1016/j.physleta.2008.07.033
Abstract
Here we demonstrate that photons launched into a specially designed metamaterial waveguide act as massive quasi-particles, which experience strong acceleration. Laser light propagating through such a waveguide may be used as a thermometer which would measure the Unruh temperature. Moreover, the metamaterial waveguide design may be approximated by a tapered optical waveguide.
