Hi !<br><br>I was looking around the internet, when I found this -<br><a href="http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TY5-3YRWB18-P&_user=10&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=d0e66d4c232994d25c2a4c54ca295e33">http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TY5-3YRWB18-P&_user=10&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=d0e66d4c232994d25c2a4c54ca295e33</a><br>
It is a research paper published by Wayne State University, USA<br>
<br><span style="font-weight: bold; font-style: italic;">Abstract</span><div style="font-weight: bold; font-style: italic;" class="artAbs"><p>We have proposed a method of increasing
the switching speed of a light-emitting diode by controlling the
voltage across the device rather than the current through it. While the
speed of conventional current-control methods is limited by the
recombination processes in the active region, with their characteristic
time being of the order of several nanoseconds, we have shown both
analytically and numerically, that the characteristic time of the
voltage-control method can be two orders of magnitude smaller. Such a
speed is provided by a large pulsed current that rapidly removes
excessive carriers from the active region if the device is being
switched off, and injects them into the active region if the device is
being switched on.</p><span style="font-weight: normal;">I dont think RONJA already uses this.</span><br style="font-weight: normal;"><span style="font-weight: normal;">Could this be a final step towards a speed > 10mbps , may be 20 mbps if not 100 mbps<br>
I dont have access to this paper, could some one download and send it to the mailing list ?<br></span><p><span style="font-weight: normal;">Regards,<br>Deepak<br></span></p></div>
