Hall developed the first semiconductor laser diode in 1962, while working at General Electric in Schenectady, New York. [4] In the 1970s, Hall's work focused on photovoltaics and solar cells . He retired in 1987, having been granted 43 U.S. patents during his career.
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
Nick Holonyak Jr. (/ h ʌ l ɒ n j æ k / huh-LON-yak; November 3, 1928 – September 18, 2022) was an American engineer and educator.He is noted particularly for his 1962 invention and first demonstration of a semiconductor laser diode that emitted visible light.
Basov with co-workers proposed Disk laser in 1966 [8] and realized experimentally the thin disk active mirror semiconductor lasers. [9] He developed with colleaguaes the first nonlinear theory of coherent addition of laser sets. [10] N.G.Basov encouraged the researchers in nonlinear optics in Lebedev Institute who discovered the optical phase ...
In semiconductor laser theory, the optical gain is produced in a semiconductor material. The choice of material depends on the desired wavelength and properties such as modulation speed. It may be a bulk semiconductor, but more often a quantum heterostructure. Pumping may be electrically or optically . All these structures can be described in a ...
Crosslight Software Inc. is an international company headquartered in greater Vancouver, British Columbia, Canada. Officially spun off from the National Research Council of Canada (NRC) in 1995, [1] it provides Technology Computer Aided Design tools for semiconductor device and process simulations.
The laser voltage probe (LVP) is a laser-based voltage and timing waveform acquisition system which is used to perform failure analysis on flip-chip integrated circuits. The device to be analyzed is de-encapsulated in order to expose the silicon surface. The silicon substrate is thinned mechanically using a back side mechanical thinning tool ...
Jon Myer (September 29, 1922 – August 30, 2001) was an experimental physicist and inventor who received 50 U.S. patents in the fields of semiconductors, mechanics, electronics, magnetics and optics. [1] His prolific work encompassed a wide field of research and his inventions ranged from supermarket scanners [2] [3] to laser microwelder ...
