In the Research Highlights of the December 2009 issue (Nature Photon. 3, 678-679; 2009), two of the images were incorrectly placed in the text.

The image for 'Tunable and compact' should have been for 'Optically driven pump'.

The image for 'Molecular orientation' should have been for 'Chip-scale source'.

Corrected in the HTML and PDF versions, after print: 13 December 2009.
