How Edison Inspired Eli Yablonovitch to Create Four World-Changing Inventions

Eli Yablonovitch shares how Thomas Edison's approach of requiring "a thousand failed discoveries for every one that works" shaped his scientific philosophy. From solar cells to semiconductor lasers to photonic crystals to cell phone antennas, Yablonovitch reveals how each invention evolved from identifying fundamental physics concepts that others overlooked. He explains how his light-trapping concept now used in every solar panel stemmed from thinking about statistical mechanics. His strained semiconductor laser design, which initially faced industry resistance, eventually became the standard in all laser pointers and DVDs. Throughout his career spanning Bell Labs, Exxon, and academia, Yablonovitch demonstrates that true innovation comes from understanding basic physics principles and having the courage to pursue ideas others dismiss as impossible.
