[edit] To-Do
1. Draw diagrams distinguishing between 1-D, 2-D, and 3-D photonic crystals. This is a good way to represent what is meant by the term, especially to people unfamiliar with concepts related to crystals.
2. Add Seamouse and Peacock to naturally occurring photonic crystals, with related references in scientific journals. It would be nice to put an #REDIRECT Scanning Electron Microscope picture of the natural photonic crystal structures. While these are present in papers published in Nature they are probably under copyright.
3. Expand the Applications section. This is important since people not familiar with the physics will be interested in what can be done with photonic crystals. The photonic crystal fiber should definitely be mentioned in more detail and its advantages elaborated upon.

[edit] Changing the title of "Fabrication Challenges" Section
I think this should be renamed to "Fabrication" rather than "Fabrication Challenges. While it may be difficult to fabricate photonic crystals for optical wavelength, it is indeed possible using Electron beam lithography, Focused ion beam or simply an advanced integrated circuit process. The challenges can be mentioned, but I think it is more insightful to talk about how photonic crystals are fabricated, rather than simply state that it is difficult to make them. What does everyone think?

[edit] BBC Light storage article
Any scientists out there think there could be an application of this science Media:http://news.bbc.co.uk/2/hi/science/nature/4443854.stm to store light using directed propogation of electromagnetic waves, rendering them and -- instead of spontaneous emissions such as found in Photonic crystals -- allow for controlled emissions?
This application could solve the world's energy crisis, completely removing the need for fossil fuels or nuclear power in order to create light. Storing it in such a matter for later use?
Or am I making a mistaken assumption that light can be stored and delved out as needed in this manner?
I am imagining a global redirection of natural sunlight from the currently sunlit side of the earth absorbed in this manner and redirected to the other side of the planet to provide light as needed.
- Anything is possible...Why not? But we could already do this using more conventional technology such as fibre optic cables.

- Hello, wikipedia is not intended to be a general forum. Discussion should be related to the article. Perhaps you can find a general Photonic Crystals forum.

[edit] Which version of English?
Does anyone know which English governs the spelling here? At the moment it is written in two with "colour" and "fiber". Dtneilson 05:06, 20 November 2006 (UTC)
- It appears that the wikipedia guideline for spelling is rather ambiguous. It states that either English can be used, but authors should be consistent on this page. As of now, there is one "color" and several "colour" on this page. Personally, I would not mind changing it to the American spelling, but I think this minor issue can be overlooked until the article is more developed.

[edit] Bunch of bull
Anyone with a microscope and tools and mirrors and vapor deposition equipment can create it. What do you see as an application of it?
- Are you claiming that Photonic Crystals are easy to fabricate? Also, are you inquiring about applications of Photonic Crystals? Your "it" leaves much ambiguity.
