What is a single-emitter laser diode?
A single-emitter laser diode is a laser diode that emits light from only one emitting region (also called a single ridge) and contains only one laser diode per package. They are usually Fabry-Perot laser diodes and can be multimode or single mode. They are available in both free-space and fiber-coupled packages.
