Summary:Emittance is one of the fundamental optical quantities characterizing optical metasurfaces. Optical metasurfaces with high emittance have been demonstrated to be very efficient for enhancing light emission of fluorescent molecules and rare-earth ions, strongly suggesting that the metasurfaces are useful to make light-emission materials more efficient. In particular, we found so far that stacked complementary metasurfaces are able to exhibit thousand-fold larger emission intensity in a quite uniform manner than non-enhancing bulk substrates like Si. We survey our recent progress in the high-emittance metasurfaces.
