Fifty years ago, summer 1962: in three independent laboratories of the US East Coast, almost simultaneously, IR coherent light was for the first time emitted from semiconductor crystals. No theory was associated with these results. Two years before, Georges Duraffourg and Maurice Bernard had ...
The history of semiconductors is presented beginning with the first documented observation of a semiconductor effect (Faraday), through the development of the first devices (point-contact rectifiers and transistors, early field-effect transistors) and the theory of semiconductors up to the contemporary ...
There followed the blossoming of II-VI, III-V and IV-IV research out of which Holonyak’s first GaAsP red LED sprang. John von Neumann had theoretically considered the essential elements of a semiconductor laser in 1953, and in 1961 it had been known for some years that GaAs p-n junction...
Since the invention of the first working laser in 1960, development of these devices has progressed at an unprecedented rate, to the extent that the laser is now a common part of everyday life, from the semiconductor laser used in CD players and telecommunication systems to the high power exi...
Since its first successful operation in 1960 at Hughes Research Labs, the laser technology has been at the center of innovation and research. Semiconductor lasers first made their appearance in 1962 when Robert N. Hall introduced the firstgallium arsenidelaser diode.1Early semiconductor lasers would ...

Introduction In the history of optical fiber communication, optical fiber with transmission loss of 20 dB/km and continuous oscillation of semiconductor laser at room temperature emerged in 1970, and the year 2020 marks 50 years since then. This paper looks back chronologically over the evolu- ...
