'''Fotoniske krystaller''' er periodiske [[dielektrisk]]e eller metal-dielektriske (nano)strukturer som er designet til at påvirke [[Elektromagnetisk bølge|elektromagnetiske bølger]]s (EM) udbredelse på den samme måde som den periodiske potentiale i et [[halvleder|halvledende krystal]] påvirker [[elektron]]ernes bevægelse ved at definere tilladte og forbudte elektriske energibånd.
 
*[http://www.cerncourier.com/main/article/44/1/15 CERN Courier: Photonic crystal makes flat lens] Citat: "...The key to creating the flat lens lies with the recent advent of materials - photonic crystals - that effectively have a negative index of refraction...the principle could herald a revolution in optics..."
*[http://news.bbc.co.uk/1/hi/sci/tech/1099278.stm BBC News: 3 January, 2001, Sea mouse promises bright future] Citat: "...The sea mouse, or Aphrodita, has spines that normally appear deep red in colour. But when light falls on a spine perpendicular to its axis, stripes of different colours appear - strong blues and greens..."The simple structure responsible for this effect is a remarkable example of photonic engineering by a living organism."..."These structures may have application in photonic communications, where there is much interest in fabricating photonic crystal fibres with similar morphology."..."
