Abstract

We report on the experimental demonstration of the broadband “trapped rainbow” in the visible range using arrays of adiabatically tapered optical nanowaveguides. Being a distinct case of the slow light phenomenon, the trapped rainbow effect could be applied to optical signal processing, sensing in such applications as spectroscopy on a chip, and to providing enhanced light-matter interactions. As an example of the latter applications, we have fabricated a large area array of tapered nanowaveguides, which exhibit broadband “trapped rainbow” effect. Considerable fluorescence enhancement due to slow light behavior in the array has been observed.
