The Function of the Unused Pin in a Laser 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.

How to connect a laser diode
You can learn to connect and program a laser diode with Arduino in this tutorial. Laser modules emit highly focused beams of light, making them ideal for a wide range of applications. This makes the laser beam very powerful and useful for many things, such as cutting or engraving materials, reading data, or even playing. The purpose of this laser diode tutorial is to provide the information necessary to create a long lifetime, stable laser diode system.

The function of diodes in fiber laser sources
A fiber-coupled laser diode is a semiconductor device that generates coherent light, which is then focused and aligned precisely to be coupled into a fiber optic cable. The core principle involves using electrical current to stimulate the diode, creating photons through stimulated. Fiber-coupled laser diode : this tutorial provides an overview of the technical properties of fiber-coupled laser diodes. Active fibers are doped with rare-earth elements (like Erbium, Ytterbium or Thulium) which perform the stimulated emission by transforming the laser diode pump to a ~6μm fiber laser core.
