Wavelength-scale objects usually diffuse incident light into all directions, thereby resulting in a low transmittance accompanied by a thick haze. The degradation of visibility remains a more challenging problem for metal nanostructures due to the ex

An electromagnetic wave with a single wave vector can be converted into multiple partial ones, with discrete or continuum wave vectors, by means of diffraction or scattering elements; this phenomenon is called optical diffusion. Optical diffusion is

We propose a systematic strategy that enables analysis of the outcoupling efficiency through each extraction route for two-dimensional (2D) patterned thin-film optical emitters with transparent substrates. Full-vectorial simulations combined with the

We developed hybrid Ag nanodots (NDs)/Ag nanowires (NWs) electrodes for enhancing the light output power of near ultraviolet (NUV) AlGaN-based light-emitting diodes (LEDs). At 385 nm, 10-nm-thick ITO-only films deposited on p-GaN/sapphire gave a tran

In this study, we introduced mesh-patterned Ag grid (width: 1520m) to enhance the light output power of near ultraviolet (385nm) AlGaN-based light emitting diode (LEDs). The Ag grid was intentionally agglomerated by annealing at 500C for 1min in air.

We studied a high-accuracy hybrid optics modeling for macroscopic lighting devices containing highly diffractive elements. For a two-dimensional (2D) grating, we achieved forward and backward diffraction distributions at omnidirectional incidence by

Breaking the total internal reflection far above a critical angle (i.e., outcoupling deep-trap guided modes) can dramatically improve existing light-emitting devices. Here, we report a deep-trap guided modes outcoupler using densely arranged microstr

An oxide/metal/oxide multilayer film serves as an ultrahigh figure-of-merit transparent electrode only for visible light. Here, we report a metal-based near-infrared transparent electrode using a two-dimensional deep-subwavelength metastructure.
