Trapped rainbow effect in visible light left-handed heterostructures

Abstract: We experimentally demonstrate the trapped rainbow in tapered left-handed heterostructures (LHHs) at visible frequencies. The employed left-handed metamaterials (LHMs) are isotropic with the size of hundreds of square millimeter. Specifically, the LHMs sample at visible frequencies has a broad spectral range and low loss, making it an intrinsic optical response for the LHHs. It is found that the frequency components of the wave packet separate at positions with different guide thicknesses only if the inclinatio… Show more

“…However, for a conventional quantum EIT effect, the media in use are often ultra-cold or ultra-hot gases, which limit the application of EIT effect, although solid-state media are believed to exhibit the EIT effect in theory [102].…”

“…It has many potential applications ranging from optical information storage to enhanced light-matter interactions [14]. Several structures for realizing wideband trapping have been proposed, including metamaterial waveguides [13,15], plasmonic waveguides [16], metal-coated optical nano waveguides [17] and plasmonic gratings [18,19]. However, these structures may suffer inevitably a serious problem of optical loss due to constituting metals, which are rather lossy especially in the visible regime.…”
