To a Great Future
There’s a Great Future in Photonics. Let’s do something about it. Of course, it was plastics that had a great future and gave us such a memorable line from the 1967 film “The Graduate.” But before we know it, the word photonics will be on everyone’s lips. I call your attention to the open letter from John Dudley, opposite this Editorial Comment, about the...
