Figure captions are a part of the electronic manuscript and
should appear after the references. They should be input
sequentially in the order in which they are cited in the text;
REVTeX will label and number the captions Fig. 1, Fig. 2, etc.
Please place the figure captions at the end of the manuscript.
The label command is used to cross reference figures
in the text. This command is inserted after the text of the figure
caption and before the final curly bracket.
Figures are cited in text with the use of the ref command.
Figures and illustrations are submitted as originals or glossy prints. Follow the rules elaborated in the Information for Contributors sections that appear in most issues of OSA's journals.
