Abstract [en]

A hyperbolic metamaterial waveguide can reduce the group velocity of light down to zero by tuning a waveguide structure. The light trapping capability of a tapered hyperbolic metamaterial waveguide is comprehensively studied in this work. Although a pulse of light cannot be trapped forever in such a waveguide, the duration that light remains trapped can be flexibly prolonged by adjusting the volume filling ratio of the metamaterial or the material dispersion, in order to achieve a sufficiently long trapping time for practical applications.
