This Figure shows three electromagnetic modes (blue, green and red) with a distance scale in microns along the x-axis. The wavelengths chosen were 450 nm, 550 nm and 750 nm, respectively. I generated the data for this image using my own computer program (written in C on 25 September 2006) and I visualized them on the same day using the GPL plotting program Grace. Hence, it is my own work, and I hereby release it under the GFDL license; have fun with it! ;)
