This site is has been moved. I'm now in process of changing my crassly commercial "buy me" links to Amazon. If you have problems, please contact me at [my first name].[my last name]ATsff.net.
There's really just one of me, but I do a variety of things. Most of my work is writing about science and technology. My writing for the general reader is published in New Scientist magazine, in books and sometimes in other places. I also write about fiber optics, lasers, and optics, in books and for Laser Focus World, as well as occasional articles elsewhere. I sometimes teach short courses on fiber optics, or consult about fiber-optic technology. (I used to do more of that before the bubble collapsed.) In my copious spare time, I write short science fiction. Other pages on this site tell more about these activities.
Oxford University Press last year published my latest book, Beam: The Race to Make the Laser, which tells how the idea of the laser was translated into reality. The starting gun was a fateful conversation between Charles Townes and Gordon Gould shortly after the Soviet Sputnik launch in October 1957. Their conversation defined the basic goal, which Gould called "light amplification by the stimulated emission of radiation" -- or LASER, a term borrowed from the microwave version, or MASER, which Townes had invented earlier. Townes and Gould each figured out how a laser should work, launching ambitious programs at Bell Labs, TRG Inc., and Columbia University. But the winner of the race was Theodore Maiman, who in 1960 built the first laser around a little cylinder of ruby. His design was so simple and elegant that TRG built their own version within weeks after seeing a press-release photograph.
The fifth edition of my tutorial introduction to fiber-optic technology Understanding Fiber Optics is now available from Prentice Hall. It's widely used for technician training and self-study, and is the place I suggest starting if you want to learn about fiber optics. (Sure, I'm biased, but I've worked hard to make it accessible to anyone who wants to understand fiber optics. That means intuitive verbal explanations, diagrams that show how things work, and simple worked-out examples.) Laser Focus World published a series of excerpts from the third edition in 1999 and 2000, and continues to publish my articles on the latest fiber-optic technology.
Order Understanding Fiber Optics (5th Edition)
My book on the history of fiber optics titled City of Light was published in Spring 1999 by Oxford University Press. It tells how the technology developed from early demonstrations of light guiding in flowing jets of water , through instruments that allow physicians to look inside the stomach without surgery, to the communication fibers that provide the backbone of today's global telecommunication network. There are tales of bright ideas, hard work, disappointment, and triumph. The cast ranges from the college undergraduate who made a key breakthrough to eminent professors of physics and independent-minded entrepreneurs. I had a lot of fun writing it, and I hope you'll share that feeling when you read it. The trade paperback edition includes an epilogue on the Boom, the Bubble, and the Bust, in which spectacular advances in fiber-optic technology create more telecommunications transmission capacity than anyone can use, and the industry runs full-speed off the cliff to land in reality with a resounding splat.
No e-mail adderess is 100% reliable, but the best way to contact me is to send e-mail to me at [insert my first name]@jeffhecht.com. (Just trying to confuse the spammers' e-mail harvesting robots.) My postal address is: 525 Auburn St., Auburndale, MA 02466 in the Boston area; 'snail mail' is not as fast, but the Postal Service has fewer inexplicable black holes than the Internet.
This is the home page of www.jeffhecht.com, now hosted at sff.net. I've switched servers, and you shouldn't notice any difference except this introduction.
You did. I also own that domain and use it as a backup domain address, which is set to forward you here.
You're thinking of http://www.sff.net/people/jeff.hecht/ . Sff.net is now hosting jeffhecht.com, so that page is linked to the jeffhecht.com domain. (Or it will be when I get things set up properly.)
My privacy policy is simple -- I don't collect any personal information on visitors, and I don't know who you are unless you send me e-mail. My site sets no cookies, and contains no legalese.However, I am not responsible for what happens if you follow links to other sites, including those of Amazon.com. I don't make the rules there.
This site is supposed to be plain and simple. It's been designed with minimal graphics and no fancy stuff so it loads fast on any Internet connection and should work on most browsers, so you don't need broadband or the latest and greatest hardware and software. I reserve the right to add more pictures, but I have no plans to do fancy things that make it slow to load. If something looks strange, that probably means something is wrong -- please e-mail me at [insert my first name]@jeffhecht.com and tell me what you're seeing and what you're using. If that e-mail bounces, try jhecht at the domain nasw.org. I try to comply with Internet accessibility guidelines and to make these pages readable with all browsers, but I can't check everything. Feedback is welcome.
I make my living writing, so I will not clutter my pages up with ads. The Amazon links are here to make it easier to find my books. Much as I might like them to be in the best-seller racks at your neighborhood bookstore, they aren't, and I don't like to hear horror stories about the books you couldn't find.
