High-speed communication technology has taken another big step forward - a research team at the University of Illinois in the United States has made important progress in laser communication technology, which can transmit data at high speed and accurately through optical fiber systems, reaching a speed of 40G per second, which is the highest speed record
in the United States in this field.
The research team that led to this was led by Professor Milton Feng, the university's "Nick Holoniac" Professor of Electrical and Computer Engineering, along with postdoctoral researcher Fei Tan, and graduate students Mong-Kai Wu and Michael Liu
.
The research group published their findings
in the Institute of Electrical and Electronics Engineers (IEEE) journal Photonics Technology Letters.

As computer technology moves towards the level of petaflops or even higher, the processor speed has exceeded the transmission speed, which creates a technical bottleneck in the application field and hinders the further development of
the application.

In today's big data and cloud computing, there is a lot of information interacting

A laser device, vertical cavity surface-emitting lasers (VCSELs), can be used to transmit data
at high speeds in fiber optic networks.
It can transmit larger amounts of
data at faster speeds than conventional cable systems.
Professor Milton Feng said: "VCSEL is the current industry standard
.
All optical interfaces today use this technology
.
The world competes in this regard mainly to find ways to improve its speed and efficiency

This time, we achieved the highest transfer speed

So how fast is this transfer? For comparison, home high-speed networks can reach speeds of about 100 megabytes per second, while Milton Feng's team achieves speeds of 40 gigabytes per second, which is 400 times
the speed of the former.
Due to its small size, the VCSEL unit is also highly energy efficient – it is up to 100 times
more energy efficient than conventional wires.
At the same time, however, the accuracy of the transmitted data is very high, and no errors
are detected during the operation of up to 1 hour.

High-speed and accurate data transmission is key to creating personalized medicine, cloud computing, and many other applications
.
For example, in order to harness the high-speed computing power of supercomputers to serve customized medicine, medical data
needs to be collected from patients first.
But the data itself is of little use, it needs to be analyzed
in the first place.
The data must then be sent from the lab to a computer facility, where the computer analyzes the data and forwards it to the patient's attending physician to help develop a treatment plan

Milton Feng said: "If you can't transmit information, then that information will be useless
.
If you can't transfer data, you're generating garbage, so data transfer technology is crucial
.
High-speed data transmission will help the better development of
remote computing, telemedicine and distance education.
It all depends on how fast you can transfer data

The VCSELs devices used by the University of Illinois research group operate at room temperature, so the next step will be to find ways to adapt the device to future high-temperature data center environments
.
.
Professor Milton Feng believes that eventually researchers will be able to increase the data transfer speed of VCSEL-based devices to 60 gigabytes per second, but after that, the room for improvement will be very limited
due to the limitations of the material itself.
But he himself is not worried about approaching the limits of VCSEL technology, because as early as 2004, Milton Feng and Professor Holoniac developed a new method that did not require VCSEL equipment: transistor lasers
