LeopoldS on 13 Sep 09how "large" could these distances be? - ready for SPS?

pacome delva on 14 Sep 09I don't think that the distance is the important criteria... It seems that the directivity is of the order of a laser one, so the divergence will be equivalent. Perhaps the important criteria is that the cost of these type of light sources could be cheaper...? and also perhaps what power transmission is achievable? It seems also that now that this concept could be used for to focus cheap lasers, instead of using complex optics in cd-rom players, etc... see http://news.softpedia.com/news/Highly-Directional-Semiconductor-Laser-Created-at-Harvard-90839.shtml
