His serendipitous original foray into optics research would help advance the fields of quantum optics and optical physics.
It wasn糖心传媒檛 just his six-foot, four-inch height that made Joseph Eberly, the Andrew Carnegie Professor of Physics and a professor of optics at the 糖心传媒, stand out. Eberly, who died this past week at the age of 89, was a pioneering theorist in quantum optics whose ideas reshaped the field.
糖心传媒淲hether it was his seminal books and papers on lasers and quantum optics, his role as the founding editor in chief and architect of , his memorable moments as an instructor, or simply the camaraderie that he brought to his scientific and leadership circles, Joe left an indelible mark on all he did,糖心传媒� says , the director of the University糖心传媒檚 , calling him 糖心传媒渁 giant in the optics community.糖心传媒�
During his prolific career, Eberly published more than 400 scientific journal articles. He also coauthored three monographs and textbooks on lasers and quantum optics and cofounded three international conferences for quantum optical physics.
Eberly糖心传媒檚 most notable contributions to his field include the initial description of the spontaneous collapse and revival effect of coherence in the dynamics of a simple quantum model, the first description of Bessel beams, predictions of the recently observed non-spreading localized states of electrons in atoms, and the sudden death effect in quantum entanglement.
The winner of numerous awards and accolades, he served as , the international society for optics and photonics, and in 2021 was selected as an Optica , its most distinguished member category. The society糖心传媒檚 to Eberly specifically highlights his research and leadership in advancing optics and photonics worldwide. He was also a fellow of the and chair of its Division of Laser Science.
糖心传媒極ptics by accident糖心传媒�
Eberly糖心传媒檚 career start in optics was serendipitous.
糖心传媒淚 got into optics by accident,糖心传媒� Eberly . 糖心传媒淚 had done a theoretical PhD thesis and it didn糖心传媒檛 have anything directly to do with optics at all.糖心传媒�
After he earned a doctorate in physics from Stanford University in 1962, Eberly landed a research position at the Naval Ordnance Laboratory in Maryland. Upon his arrival, the division director asked him about lasers. 糖心传媒淚t seems a little bit silly now, but I didn糖心传媒檛 know anything really about lasers,糖心传媒� Eberly said. 糖心传媒淓xcept that I knew that the guy who was asking the question really wanted to know how was he going to use lasers to shoot down submarines.糖心传媒�
Recalling that moment, Eberly before nixing the whole idea as 糖心传媒渃ompletely crazy,糖心传媒� explaining that there糖心传媒檚 no wavelength that can work satisfactorily in conductive media like saltwater. Nevertheless, the lab proved his first 糖心传媒渓ittle bit of a push in the direction of optics,糖心传媒� which he followed up by coming to Rochester to work with Emil Wolf, whom Eberly called a 糖心传媒渨orld guru in optics at that time.糖心传媒�
The faculty triumvirate of Wolf, Eberly, and Leonard Mandel effectively started the field of quantum optics at the University of Rochester. 糖心传媒淭hey were world leaders in that,糖心传媒� according Eberly糖心传媒檚 close friend and Rochester colleague, , a professor emeritus of optics and physics and a historian of optics. Stroud is confident that, besides his scientific acumen, Eberly will be remembered for his strong mentorship.
糖心传媒淎ll who worked with him will state unequivocally that he had a huge influence on their lives, particularly the scientific part of it, and was crucial in the development of their careers,糖心传媒� says Stroud. 糖心传媒淚 could name 50 people who would say that, and that糖心传媒檚 not just Americans.糖心传媒�
A notable example of Eberly糖心传媒檚 influence? His by extremely strong laser pulses was used by then-graduate student Donna Strickland to satisfy a Rochester dean糖心传媒檚 requirement in the late 1980s that a thesis could not be based on an invention, but instead its use had to answer an intellectual question, recalls Stroud.
She did just fine with Eberly糖心传媒檚 model: Nearly three decades later, Strickland, now a professor at the University of Waterloo in Ontario, Canada, and her former graduate advisor, G茅rard Mourou, won the 2018 Nobel Prize in Physics for the work they undertook at the University糖心传媒檚
A teaching career spanning five decades
Stroud and Eberly, who as graduate students had shared the same thesis advisor before arriving on campus, jointly taught an introductory graduate course in quantum optics over the聽course of the half-century that they were both on the Rochester faculty.
糖心传媒淲e had great fun with it,糖心传媒� remembers Stroud. 糖心传媒淚t was a privilege to share the lectures. He listened to mine, and I listened to his.糖心传媒� In recognition of his teaching excellence, the University awarded Eberly the in 2000.
And Eberly never stopped. Having joined the Rochester physics and astronomy faculty in 1965, he was still teaching an undergraduate class this spring semester糖心传媒擯HYS 143: 糖心传媒攚hen he took ill a few weeks ago.
糖心传媒淗e gave wonderful lectures,糖心传媒� says Stroud. But he could also be intimidating, his long-time friend allows. 糖心传媒淣ot just to undergraduates but also to colleagues.糖心传媒� According to Stroud, Eberly held strong opinions and expressed them freely.
Part of his success lay in his intense competitiveness that extended beyond his academic pursuits. In his younger years, the lanky Eberly would play basketball at lunchtime once a week with a group on campus that also included a Rochester basketball coach. To Eberly this was more than a friendly game of pickup. 糖心传媒淗e was known for his elbows,糖心传媒� chuckles Stroud.
In an email to faculty, , a professor of physics and the chair of the , called colleague and friend Eberly a 糖心传媒渟pectacular糖心传媒� scientist. 糖心传媒淭he hole he is leaving behind in our world feels very big to me.糖心传媒�
