If you don't have a VRML viewer for your web browser you'll need to go and get one, the one I use is from Silicon Graphics : Cosmo Player. (http://cosmosoftware.com) If you like what you find here but would like me to make a particular crystal let me know. As I continue to study different crystals I'll update this page and others, check out the gallery page for other VRML examples. Here are the crystals so far, most come in chunks so that you get the feel for a bulk piece of crystal :

Simple 2D Structures
 

	Square Lattice of Dielectric Bars (1k)
	Square Lattice of Dielectric Cylinders (1k)
	Dielectric Cylinders with a defect as suggested by Villeneuve et Al, Phys Rev B Vol 54, No 11. (3k)

Woodpile / Log Pile / Scaffold Structures
 

Bars
	3D Woodpile Structure (FCT General Definition)  (2k)
	100 GHz Woodpile as suggested by Ozbay et Al.  Appl Phys Lett, 1994, Vol 64 No 16 (3k)
	500 GHz Woodpile as suggested by Ozbay et Al. Optics Lett. 1994 Vol 19 No 15 (3k)
Cylinders
	Ozbays 100GHz system as above but with cylinders (4k)
	Ozbays 500GHz system as above but with cylinders (4k)

Problems ?

When you click on the links below if the files list to the screen and don't start your VRML viewer automatically then you'll need to do the following:

Save the .wrl files on your own computer, (either use the Save Link As from your right mouse button for PC users or shift click the link). Once you have saved the file(s), use File and Open from your web browser to open up the .wrl file that you have saved onto your hard disk.
