This chapter starts with a brief recap of the fundamental aspects and elements of diode lasers, including relevant features of the standard device types, with an emphasis on the advantages of quantum heterostructures for their effective use as active regions in the lasers. Operational Mechanism: Laser diodes create light through stimulated emission within an optical cavity, with the light's properties influenced by the semiconductor. Laser diodes offer high power for their size and produce electrical-power-efficient laser radiation. It works on the same basic principle as an LED, but with an internal structure that forces photons to align in phase and direction, producing coherent laser light instead of the.

Because VCSELs emit from the top surface of the chip, they can be tested on-wafer, before they are cleaved into individual devices. This reduces the cost of the devices. It also allows VCSELs to be built not only in one-dimensional, but also in two-dimensional arrays. The larger output aperture of VCSELs, compared to most edge-emitting lasers, produces a lower divergence angle of the output beam, and makes possible high coupling efficiency with optical fibers.
