Experimental observation of the trapped rainbow

摘要

We report on the experimental demonstration of the broadband “trapped rainbow” in the visiblenfrequency range using an adiabatically tapered optical nano waveguide. Being a distinct case of thenslow light phenomenon, the trapped rainbow effect could be applied to optical computing and signalnprocessing, such as spectroscopy on a chip, and to providing enhanced light-matter interactions.n© 2010 American Institute of Physics. u0004doi:10.1063/1.3442501
