A 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 regions respectively. While initial diode laser research was conducted on simple P–N diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in order to maximiz
The Diode Laser
The form of the p-n junction in the first GaAs laser diodes was relatively conventional, consisting of an n-type GaAs “host”crys-tal into which Zn atoms were diffused to create a heavily doped p+ region.
