Talk:Photonic crystal/to do

• This picture[1] is a good example of a 3-D photonic crystal. I think it can be used on this page without copyright problems, since the work has been done at a government lab.

• 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.

• Add Seamouse and Peacock to naturally occurring photonic crystals, with related references in scientific journals. It would be nice to put an Scanning Electron Microscope picture of the natural photonic crystal structures. While these are present in papers published in Nature they are probably under copyright.
• 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.

NewScientist reports on a color-changing liquid thatcould cheaply replace the color components of standard LCDs

A liquid that changes colour when exposed to a magnetic field could cheaply replace the colour components in conventional LCD monitors, claim US researchers.... ...The opposing forces of electrostatic repulsion and magnetic attraction result in the particles arranging themselves into an ordered structure, known as a colloidal "photonic crystal".

• Re-write the main heading section to remove reference to semiconductors. Explaining what a photonic crytsal is by comparing it to the (equally opaque) subject of semiconductor band-structures in the main heading seems odd to me. DMB (talk) 11:40, 8 April 2008 (UTC)
• Rewrite "Computing Photonic Band Structure" section as a "Theoretical and computational methods for photonic crystals" section - although even then, it must be noted that these methods are not unique to photonic crystals, and so this section should be kept brief.
