Cross-sectional schematic of the hybrid device structure (not to scale).
(a) Angle-resolved spectral intensity map of a device based on a GaN micro-LED emitting at 405 nm. Inset: angular dependence of the color-converted photon intensity. (b) Map of the wavelength- and angle-dependent enhancement of the color-converted light from a device based on a micro-LED emitting at 450 nm. Inset: polarization resolved spectra in direction normal to the sample surface.
Conversion efficiency and pump attenuation of patterned and unpatterned films integrated onto a GaN LED emitting at 405 nm.
Temperature dependence of the photonic stopband wavelength of the PhC.
Optical −3 dB bandwidth of the green emission from LED pumped polymer compared to bare LED at different LED currents. The insets show corresponding eye diagrams at 350 Mb/s, (50 mA), and 450 Mb/s, (70 mA), respectively.
