Prof. Eli Yablonovitch (University of California, Berkeley) is Director of the NSF Center for Energy Efficient Electronics Science (E3S), a multi-University Center headquartered at Berkeley.
Yablonovitch introduced the idea that strained semiconductor lasers could have superior performance due to reduced effective mass (holes). With almost every human interaction with the internet, optical telecommunication occurs by strained semiconductor lasers.
He is regarded as a Father of the Photonic BandGap concept, and he coined the term "Photonic Crystal". His discoveries include 3-dimensional structure with photonic bandgap (so-called, Yablonovite), “Yablonovitch Limit” for light-trapping in photovoltaics,etc. He is co-founder of Alta Devices Inc. (that produces world record GaAs solar cells) and Ethertronics Inc. Ethertronics (that shipped over 1.7 billion antennas) and other companies.
He was elected to NAE, NAS, NAI, AmAcArS, and Foreign Member, UK Royal Society.
