1.1 Laser Diodes: A Very Brief History
(yes, even before the internet) and the history of the semiconductor laser diode is strongly tied in with that of fiber optics and optical telecommunications (Hecht 1999).
Get QuoteA laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regi...

The laser is unique in that its entire structure is manufactured a layer of atoms at a time by the crystal growth technique called molecular-beam epitaxy.
