OPTICAL TRANSISTORS

Last week, a Danish team working at Harvard and the Rowland Institute in Cambridge reduced the speed of light to 38 mph — which, of course, is the aspect of their work that got the consumer media all in a tizzy. Not that that part isn’t interesting, of course, but much more interesting was how it was done, and what it means.
     First, having cooled a cloud of sodium atoms to about 50 billionths of a degree above absolute zero, they shot a laser beam into the cloud at exactly the resonant frequency of the atoms. Because this was the resonant frequency, the beam was completely absorbed (the cloud became opaque to the beam), and one can surmise that the energy thus absorbed was converted to a higher energy state of the sodium — although not likely to have shown up as kinetic energy (heat).
     (Note: lasers have long been used to cool and homogenize the kinetic energy of such clouds by slowing fast oncoming atoms and speeding slow departing atoms.)
     Now jump for a moment to classical quantum mechanics: light cannot interact with itself, since all light waves are just superimposed on each other. Not much use in computers.
     But this week the Danes did something different: by tuning the first laser to the resonant frequency of the atoms, and then shooting in a second tuned laser at a different frequency, the second beam actually interacted with the resonant soup. Result: the second beam passed about 25 percent of its energy through the soup, at a speed of 38 miles per hour. This is similar to using one stream of electrons to control the flow of another, which happens to be the basis for all modern transistors.
     Cocktail Party Summary: using light/matter resonance, optical transistors (and computers) are a step closer to reality.

JAVA GOES FREE — ER, OPEN

After an awful lot of talk about how it supports Open Source Software (OSS), Sun finally released its Java source code last Friday — a couple of years after the open source conversation first began.
     The code is now posted on the company’s Web site. But, as expected, there are a few hooks in the new Community Source License agreement — which any reseller must sign — that will quickly distinguish this offer from that of Linux or other OSS efforts. To wit: all resellers of Java must still pay a license fee to Sun; all resellers must sign an agreement controlling usage of Java. Extensions or enhancements of Java are strictly verboten.
     Did I say “open?”
     Except that source code is available, this is the business model of a closed system in all other respects. Ain’t marketing grand? You can download it, do whatever you want with it, then ask Sun’s permission to approve any changes you made, then pay Sun, then give up your rights to those changes ….
     Oh, I get it: you do the work, Sun gets the money. Seems fair enough.
     In a related white paper, Sun visionary Bill Joy says he is looking for a new business model. Keep looking, I’d say — this one’s old.

CALIFORNIA: A Y2K MINIVERSE

I have long suggested that the Year 2000 problem will be focused on smaller entities in general — smaller firms, countries, states, that have no budget for compliance assurance — and that this will give a sharp competitive edge to those groups who have already solved their problems.
     Enter California. It is hard to call the Golden State a small anything, and yet this week, the California Bureau of State Audits released a report noting that “14 of 20 critical agencies” had not yet tested systems for compliance.
     Oops.
     This brings up a level of competition that we probably should all think about, and which isn’t patently obvious. How is Louisiana doing on Y2K? How is Yoknapatawpha County doing? How is your town doing?
     Although your town does not compete directly with Thailand, it is likely that some of your towns, at least, are as poorly equipped as some poorer countries when it comes to Y2K readiness. What does this mean? If towns cannot provide services, neighboring boroughs may be called to do so. Will they charge? You bet. This is called competition.
     If counties cannot provide services, neighboring counties will not be of much assistance. But the turmoil may cause long-term competitive disadvantage, after all the dust settles.
     And if states cannot provide services: well, that’s where things get serious. To a citizen, there is no difference between services provided by the state and the federal government. These problems will be solvable, and are not cause for panic; but heads will roll, and fortunes will change hands, based on the outcome.
     Looks like new California Gov. Gray Davis has his work cut out for him. And you can assume those heads will start rolling before the end of the year.
