Abstract
Erroneous absolute luminance values of the pixelated phosphor structure B25 (pixel size of 25 microns by 25 microns) have been corrected. The updated figure shows clearly the potential of the investigated structure as light-converter for high-resolution lighting systems.

The absolute luminance values of the pixelated phosphor structure B25 (pixel size of 25 microns by 25 microns), as shown in Fig. 8 of the main article [1], are erroneous. As the absolute values are not important to show the potential of this structure as light-converter for high-resolution lighting systems, the luminance values have been normalized to unity. The original figure is corrected accordingly (see Fig. 1).
Fig. 1 Normalized luminance of structure B25 under low-power excitation at 442 nm. The incident angle of the laser excitation is 60° to the surface normal, the detection is in direction to the surface normal. (b) Normalized luminance profile of structure B25 along the line indicated in (a). The vertical dashed lines indicate the position of the silicon walls between the pixels. The normalized luminance profile of structure A2000 is added for comparison.
