We can call the last decade as the fiber laser optics era. Almost all the devices that form part of our daily life rely of fiber optics technology. Our cell phones, pagers, fax machines and out Internet connexions are the final results of large research on fiber optics, laser and the quantum mechanics of Einstein. He came up with the principle of stimulated emission, which means that electrons could absorb and emit energy of photons at a single frequency. Later on, this was developed to create the microwave emission, and then, this was applied to visible light and finally landed on laser.
Since fibers optics laser light could not produce a steady light, scientific led their research focus towards semiconductor lasers that allowed the continuous laser operation. But their complication was on how to transmit this light through long distances. They first considers glass fiber since it was already known as a long distance light transmitter, however there was a problem: light loss. So they continued exploring how to take fiber optics communications out of the lab into real life without the problem of light loss.
It was recently in the 70ís that fiber optics massive commercialization started worldwide and fiber optics became a technological specialization that demanded qualified training fiber optics. This technological is still in continuous fiber optics test equipment research development, especially by telecommunications companies which dream of a whole fiber optics network to assure the liability of their customers, cost reduction and process optimization and of course, the growth of their finances until a new technology arrives.
Fiber optics is a promising field, and it will be long for a considerable time; but there still persists the problem of making it available to great mass and the large infrastructures and the most faraway places. The challenge is here, and companies have decided to take it because the demand compels so: People want more speed, bandwidth and efficiency for fewer costs, and this is the fuel that makes run the research and development engine.
