Raymond Chiao is an American Physicist known for his experimental work in quantum optics.
Biography
Raymond Chiao was born in Hong Kong on Oct. 9, 1940, and moved as a child to the United States in 1947. He grew up in New York City, where he attended Collegiate School. It was there that he first got interested in science through reading Gamow’s book One, Two, Three, ..., Infinity.
He was admitted to Princeton University in 1957 as an electrical engineer, but then switched to the physics department, where he worked unsuccessfully with John Archibald Wheeler on a senior thesis project on the quantization of general relativity. He then switched from theoretical physics to experimental physics in graduate studies at MIT under the supervision of Charles Hard Townes, shortly after the experimental realization of the ruby laser. His thesis topic was on the first observation of stimulated Brillouin scattering.
After obtaining his Ph. D. in 1965 from MIT, he taught as an assistant professor there until 1967. He moved to UC Berkeley in 1967, and remained there until 2006, after which he took a position at the UC's newly opened campus UC Merced.
Discoveries
Chiao has become well known in the field of quantum optics due to several important experiments. He was first to measure quantum tunnelling time, which was found to be between 1.5 to 1.7 times the speed of light. He also was the first to measure the topological Berry's Phase (Geometric phase) .
Current Work
In a sense, Chiao never stopped working on the project his undergraduate thesis adviser John Archibald Wheeler gave him. He has recently turned his full energy on the project of detecting gravitational waves through the use of superconductors.
