Writing about Lasers, Dinosaurs, and other Science and Technology

News About Understanding Fiber Optics

Understanding Fiber Optics is temporarily unavailable, but I am in process of arranging republication of the fifth edition. I hope to have word on the republished fifth edition by the end of March. In the longer term, I am planning a major revision of the book in sixth edition, and would welcome your comments and feedback. See my Understanding Fiber Optics page for more details. -- Jeff Hecht, March 1, 2015

A Few Words of Introduction

If you ask what I do, the fun answer is that I write about lasers and dinosaurs. More seriously, I write about optics, photonics, paleontology, earth and planetary science, the environment, electronic and optical technology, and many other areas of the physical sciences. I have written several books about lasers, fiber optics, and their history, and have taught short courses and given webcasts in those fields. In my copious spare time, I write short science fiction stories.

I am in the process of updating this web site, and won't go into the long story other than to blame software problems.

What I Do

I am a regular contributor to two magazines

New Scientist, a global weekly covering science and technology. You can see my latest contributions here.

Laser Focus World, a laser industry trade magazine. You can see what I write here.

I write nonfiction books about science, technology, and their history. The most recent are

Understanding Lasers: 3rd edition, a tutorial on lasers.

Understanding Fiber Optics: 5th edition, a tutorial on fiber optic communications

Beam: The Race to Make the Laser. a history of the birth of the laser

City of Light: The Story of Fiber Optics, a history of fiber-optic communications, part of the Sloan Technology Series.

I teach tutorial short courses, present webcasts, and consult on lasers and fiber optics.


Understanding Fiber Optics

The fifth edition of my tutorial introduction to fiber-optic technology Understanding Fiber Optics is temporarily unavailable, but I am in process of arranging republication as of March 1, 2015. Please contact me if you have any questions.

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.) I am now working on a sixth edition, which I expect will take a different form. Your comments are welcome.

History of Fiber Optics

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 2004 revised and updated trade paperback edition includes an epilogue on the Boom, the Bubble, and the Bust, that unpleasant reminder that you can have too much of a good thing.
