. I learned about materials and their different spectral responses. I was ready to hit the ground running at Corning.”

Corning years

After receiving his Ph.D., Keck began looking for a job. The market was booming for physicists in 1967, as both the space exploration and weapons development industries were thriving. Keck received numerous job offers, and had no intention of working for Corning until a recruiter visited the Michigan State campus and displayed a bundle of optical fiber. Intrigued by the fiber, Keck visited Corning Incorporated in Corning, New York
Corning (city), New York

, and met with Dr. Robert Maurer, who discussed Corning’s optical fiber development project and its goal of building a low-loss optical waveguide suitable for transmitting data. After listening to Maurer, Keck accepted an offer from Corning, moved to New York, and began work as a senior research scientist on the project in January 1968.

Optical fiber

In the early 1960s, demand emerged for a new telephone wire technology. Copper cables, which were the state-of-the-art at the time, were being pushed to their limit, as more and more telephone calls were being made. An international effort began to find the next great data transmission technology.

Initially, optical fibers – glass or plastic fibers which carry data in the form of light – were of little consideration for the job of replacing copper wires. The fibers that existed in the 1960s were high-loss; while they directed the light, they also absorbed so much of it that little of its signal remained after a few meters, rendering them useless for long-distance telecommunications. However, Robert Maurer, Keck’s boss, believed low-loss optical fiber could be produced, and made its invention his goal. Maurer’s goal was to invent a fiber with a loss, or attenuation

For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.In electrical engineering and telecommunications, attenuation affects the...

, of 20 decibels per kilometer (db/km). At the time of Keck’s hiring, the best optical fibers had attenuations of 200 to 1000 db/km.

, a chemist, approached the task differently than other researchers. Instead of trying to improve upon existing fibers by using better raw materials, Maurer sought to explore the capabilities of new materials, including pure silica. The team devised a division of labor, where Maurer focused on physics, Schultz developed new types of glass, and Keck turned this glass into fiber.

They started work on the project as soon as Keck arrived at the beginning of 1968, and had little early success. They experimented with different glass compositions and methods of heating the glass. Finally, in August 1970, the team found their breakthrough moment: late one afternoon, after both Maurer and Schultz had left for the day, Keck took measurements of the newest batch of fibers he had heat-treated. When Keck noticed the light passed through the 65 foot fiber seemingly without any loss, he exclaimed “Good grief, what do I have here?” Keck took more measurements of the fiber, and discovered it had an attenuation of 16 db/km, exceeding the goal of 20 db/km. Upon this discovery, Keck wrote in his laboratory notebook, “Attenuation equals 16 db it says. Eureka,” followed by an exclamatory “Whoopee!”. Keck and his team had invented the first low-loss optical fiber; it was composed of heat-treated titanium-doped silica. Papers were written and patents were filed, and Corning introduced the fiber to the outside world, but it would take another 10 years before the telecommunications industry began utilizing their invention.

In the meantime, Keck continued to improve upon the fiber he had invented. He replaced the titanium oxide

Today, more than 90% of long-distance data in the United States is now sent through the optical fiber Keck and his team designed and produced.

Later work

After his initial success with low-loss optical fiber, Keck continued working with Corning to make optical communications more viable. Keck was responsible for inventing numerous optical couplers and splitters, which greatly extended the applications of optical fiber. He was elected Editor-in-Chief of the industry-leading Journal of Lightwave Technology in 1989, a position he held until 1994.

Moreover, Keck began to rise within the corporate ladder at Corning. After beginning as a senior research scientist in 1968, almost 30 years later, in April 1997, Corning appointed Keck the Division Vice President of Core Technology, Optics and Photonics – Science and Technology. During his management tenure, Keck was a key figure in establishing Corning’s modern innovation ethos, and also helped guide Corning into the emerging field of photonics. By the end of his tenure with Corning, Keck was well regarded in the scientific community as an expert within the fields of molecular spectroscopy, gradient and aspheric optics, guided-wave optics, fiber optic sensor

After Corning

Keck retired from Corning in 2002, after spending 34 years with the company. Throughout his career, he served the company in numerous capacities, and at the time of his retirement he held the position of Vice President and Director of Research. Immediately after his retirement, Keck helped establish the Infotonics Technology Center in Canandaigua (town), New York
