OverviewTheoryHistoryTypesReliabilityApplicationsCommon wavelengthsFurther reading
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
Laser Diode
A laser diode is primarily built using three semiconductor layers — a P-type layer, an N-type layer, and a thin intrinsic (I) layer — forming what is known as a PIN structure.
