* [ 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..."
* [ 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."..."
