at the University
of California, Berkeley, may have
come up with a solution finally
(Science, Vol 268).
The idea is to hook up micro-scopic lasers directly onto the chips. This is achieved by a process called "fludic self assembly", where the lasers are mixed with ethanol and swished over silicon wafer on which matching shapes have been carved. The lasers fit into the holes and one gets a potential optoelectronk chip.
