• Laser diodes form a subset of the larger classification of semiconductor p–n junction diodes. Forward electrical bias across the laser diode causes the two species of charge carrier – holes and electrons – to be “injected” from opposite sides of the p–n junction into the depletion region. Holes are injected from the p-doped into the n-doped, and electrons vice versa, semiconductor
• 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 regions respectively
