Joachim used our newssubmit to tell us that Compoundsemiconductor.net reports that a Taiwanese university has developed a violet laser diode. A violet laser beam has a shorther wavelength then the current red and the upcoming blue laserbeams and this allows the beam to make smaller pits and is therefore the key to next-generation large-capacity optical disc systems.
Professor J.I. Chyi, Director of the Optical Sciences Center at NCU and responsible for the development of the laser devices explains: "The results that we recently achieved with our horizontal flow reactor are groundbreaking. The MOCVD process is exceptionally stable, which is mandatory for the development of sophisticated optoelectronic devices such as violet laser diodes and the related reproducible production process." |
Unfortunately it is not known if which amount of data we should think now, but it will likely be about 27 GB on one disc. Read the entire story here. Discuss subjects like this in our Optical Storage Technical Discussions Forum.
