Summary of work and development of light emitting diodes (LEDs) and diode lasers done in the 1950s and early 1960s at Sylvania Research Laboratories, and at General Telephone and Electronics Laboratories, 1961-1964. Semiconducting Compounds Group investigates intermetallic compounds, especially GaAs and HgTe in the 1950s. Group joins the Battelle Memorial Institute group, 1957. Group effort devoted to GaAs from 1958. Group leaders discussed, Don Wahl, Henry Minden, and Sumner Mayburg. Work prompted in part by Heinrich Welker's 1952 report on preparation and properties of III-V compounds.
The discovery of the semiconductor laser at IBM in 1962. Competition with other laboratories. Follow-up studies of the use of lasers for optical logic. Managing the research. How technology affects scientific research.
Doctoral thesis on 2-level solid state masers at Berkeley in 1956-1959 through the beginnings of his work on integrated optics at California Institute of Technology in the mid-1960s. Research at Bell Telephone Laboratories on noise, parametric amplifiers, doped crystal lasers, and semiconductor lasers, and his mode-locking studies at Watkins-Johnson and Lockheed. Role of consultancy at Hughes Aircraft Co. on research in phase-conjugated optics.
