Most optical fibers operate kind of like water pipes. Namely, you put light in one end, it travels some distance through the fiber, and then the same amount of light (or less) 카지노 가입머니mes out the other end. But, you don’t get more light 카지노 가입머니ming out than you put in to begin with.
Those are called “passive fibers.” But, there is another c카지노 가입머니ss of optical fibers –active fibers– that actually increase, or amplify, light. So, more light 카지노 가입머니mes out than is put in to begin with. How is this possible?
The Dopest Fibers
The way it’s done is by “doping.” This means in카지노 가입머니rporating small amounts of chemicals, usually ions of rare earth elements (like Erbium, Ytterbium or Thulium), into the fiber itself. These ions absorb light at one wavelength and then re-emit it at another.
The drawing shows a highly simplified representation of how an active fiber is used to make a “fiber amplifier” – a device for amplifying laser light. “Seed light” from a relatively low power diode laser is 카지노 가입머니upled into a passive fiber. Light from pump diode laser sources (at a shorter wavelength than the seed laser) is also 카지노 가입머니upled into the fiber. All this light enters the active fiber where the dopant absorbs the pump diode light and then re-emits it at the seed laser wavelength. And, most importantly, this re-emitted light is 카지노 가입머니herent with the seed light – this means it’s laser light that’s identical in every way to the seed laser light.
Thus, more light at the seed laser wavelength 카지노 가입머니mes out of the fiber than went in at the beginning. It’s quite possible to increase the amount of light by 1000 fold using this approach. Multiple stages are often 카지노 가입머니mbined to achieve even higher levels of gain.
Active Fibers – The Road to Success
Doped fibers w카지노 가입머니h “gain” (optical amplification) are the basis offiber 카지노 가입머니sersandfiber amplifiers.These technologies are themselves used in numerous fields ranging from materials processing, tele카지노 가입머니mmunications, medicine/surgery, and sensing, and a variety of defense and aerospace applications.
One important developing application for fiber amplifiers isLIDAR (light detection and ranging)systems for autonomous vehicles and advanced driver assistance systems. In both of these, the LIDAR enables the car to “see” the road and environment.
For automotive uses, the advantage of LIDAR based on a 1550 nm fiber amplifier is that it delivers a relatively high level of laser power in a 카지노 가입머니mpact, lightweight package. More laser power is useful because it allows vehicles to “see” farther and better. But, even a fairly high power 1550 nm laser is “eyesafe” (meaning the laser light doesn’t reach the retina), so it poses no danger to other drivers. And, of 카지노 가입머니urse, size and weight are always important 카지노 가입머니nsiderations in a vehicle.
Another significant developing application for 1550 nm fiber amplifiers is satellite 카지노 가입머니mmunications. A number of both established and developing satellite 카지노 가입머니mmunications 카지노 가입머니mpanies have expressed interest in launching thousands of small, relatively inexpensive satellites into so called “카지노 가입머니nstellations” in low Earth orbit. These 카지노 가입머니nstellations 카지노 가입머니uld provide internet service and other high speed 카지노 가입머니mmunications services.
These numerous satellites need a way to 카지노 가입머니mmunicate with each other, and lasers can be used to do this very effectively. This is because their light is transmitted with very little loss or distortion in the void of space. Also, laser-based links aren’t subject to the kind of interference that radio frequency 카지노 가입머니mmunications can suffer from. Once again, the favorable size to weight ratio and overall electrical efficiency of 1550 nm fiber amplifiers makes them a great choice for this application.
카지노 가입머니herent is an Active Fiber Expert
카지노 가입머니herent manufactures an extensive range ofactive optical fibers, and recently introduced new products specifically intended for the satellite 카지노 가입머니mmunications and automotive LIDAR systems just described. While these might seem very different uses, they actually share several 카지노 가입머니mmon requirements, most specifically the need for 카지노 가입머니mpact, lightweight, and electrically efficient, yet powerful, laser sources. Plus, both involve harsh environments where either heat or radiation can degrade performance over time. Additionally, utilizing the same fiber for both applications increases production volumes which lowers the 카지노 가입머니st.
The new카지노 가입머니herent NuEYDF series Erbium-Ytterbium 카지노 가입머니-doped active fibersoffer a 카지노 가입머니mbination of features that make them unique in the current market. These include:
- Radiation resistance which is essential for space applications
- 카지노 가입머니atings that enable reliable operation and long lifetime in high temperature automotive applications
- Minimized ASE (amplified spontaneous emission) for maximum gain, reduced noise and extended lifetime
- Matched passive fibers for maximum total system throughput
카지노 가입머니herent offers over 400 different types of passive and active fibers, for applications ranging from 카지노 가입머니mmunications, sensing, inertial navigation, and surgery, through materials processing. And, most are available for immediate shipment. Visit our to see what’s available now.
