John Kitching (physicist)


John Edward Kitching is a British–Canadian–American physicist and inventor, and a Fellow and Group Leader at the National Institute of Standards and Technology. His research focuses on the development of compact "chip-scale" devices such as atomic clocks and magnetometers.

Biography

Early life

Kitching was born in Chester, UK, to a physicist father and educator mother. His family emigrated to Canada when he was very young and he went to elementary and middle school in Edmonton, Alberta. He moved to Vancouver, BC, when he was 15 years old and attended Sir Winston Churchill Secondary School, winning the Governor General's Bronze Medal. He obtained his undergraduate degree in physics at McGill university in 1990, receiving the Governor General's Silver Medal for achieving the highest academic standing in the university's graduating class that year. He completed his PhD in Applied Physics at the California Institute of Technology in 1995 under the supervision of Prof. Amnon Yariv.

Career and Research

Kitching's research focuses on the development of compact devices and instruments that combine elements of precision atomic spectroscopy, silicon micromachining and photonics. In the early 2000s, he and his group pioneered the development of chip-scale atomic clocks and magnetometers based on a patent filed with the USPTO in 2001. These instruments achieve an unprecedented combination of stability/sensitivity and small size, low power consumption, and manufacturability.
Kitching has also been heavily involved in the application of his compact instruments to problems in biomagnetism and nuclear magnetic resonance. He is currently leading in the development of compact, SI-traceable standards of length, time, voltage, current, and temperature under NIST's "" program.
Several of Kitching's patented inventions have been successfully commercialized. His original chip-scale atomic clock was on display for about a decade in the National [Air and Space Museum|Smithsonian Air and Space Museum].
