Laser Amplifier: Scientists have developed an amazing laser amplifier that can transmit data 10 times faster than the existing technology. This discovery will not only take the internet speed to the skies in the future but can also play a big role in medical and scientific research.
What do laser amplifiers do?
Laser amplifiers increase the intensity of light rays. In existing telecom systems, internet signals are sent through optical fibers with their help. The capacity of data transmission mainly depends on the bandwidth of the amplifier i.e. on how many different wavelengths information can be sent.
The growing challenge of data traffic
The increasing use of streaming platforms, smart devices and generative AI is increasing the data burden every day. According to a report by Nokia Bell Labs, the world’s data traffic will double by 2030. In such a situation, it is very important to increase bandwidth.
New Technology- High-Efficiency Optical Amplification
The researchers have now designed a new high-efficiency optical amplifier with a bandwidth of 300 nanometers. In comparison, existing systems have a bandwidth of just 30 nanometers. This allows the new amplifier to transmit 10 times more data per second.
How does this amplifier work?
It is made of silicon nitride which can withstand high temperatures. It uses spiral-shaped waveguides that direct the laser pulse more efficiently and reduce signal distortion. It is miniaturized, meaning that many amplifiers can be installed on a small chip. The four-wave mixing technique used in this design combines different optical frequencies to strengthen the output and reduce noise.
Not just internet, it is also used in these areas
Although increasing internet speed is its biggest benefit, it has other uses too:
- Medical Imaging and Diagnosis
- Holography and Microscopy
- Spectroscopy and Scientific Analysis
Researchers say that with slight changes in the design, it can also be used in visible light (400–700 nm) and extended infrared (2000–4000 nm) range. This technology can help in detecting diseases quickly and accurately.
Internet of the future and science
This technology has the potential to make the internet 10 times faster than today. Also, its use in areas like health, research and space can prove to be revolutionary. The possibility of its being available in small size and cheap price can also bring it within the reach of common people.
