VCSELs are a type of semiconductor laser. They are similar to LEDs in that the light is emitted from the surface of the wafer or chip. With conventional edge-emitting lasers, the light is emitted from the edge of the chip, requiring that the wafer be sawn or cleaved, and the chip packaged, before testing.
