- Acronym for vertical-cavity Surface-Emitting laser. A laser diode that emits its coherent light from its surface, as opposed to its edge. Such lasers are simpler to manufacture and easier to test, in addition to being more efficient and durable. Since its emitted beam is narrower and more circular, it is especially well-suited for use with optical fibers.
