Silicon optical transmitter

19.11.2020

Silicon photonics experts at the Optoelectronics Research Center (ORC) have demonstrated the first all-silicon optical transmitter that operates at 100 Gbps without the use of digital signal processing.

The optical modulator almost doubles the maximum data rate of today's devices, demonstrating the potential for low-power, low-cost all-silicon solutions. They avoid the complexity of manufacturing processes using new materials that are incompatible with CMOS.

CMOS (complementary metal-oxide-semiconductor structure; English CMOS, complementary metal-oxide-semiconductor) is a set of semiconductor technologies for building integrated circuits and the corresponding circuitry of microcircuits. The vast majority of modern digital circuits are CMOS.

The optical modulator is an important component in systems serving modern information and communication technologies. And not only in traditional data communication channels, but also in microwave photonics.

In contrast to previous work in this field, the scientists introduced a new modulator design concept in which photonics and electronics must be considered as a single integrated system in order to solve complex technical problems in this field.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Synthesized a new type of antibiotic to fight superbugs 25.03.2018

The struggle of scientists against superviruses and superbugs continues - today another significant breakthrough in this area has been made, providing specialists with a lot of food for thought and a lot of material for study. The fact is that a talented team of microbiologists from the University of Lincoln, UK, managed to synthesize a new type of antibiotic that can effectively fight superbugs, being introduced as the basis for modern-class antiviral drugs.

The preliminary results obtained by specialists cannot but surprise, since they managed to defeat one such superbug in experimental mice.

This antibiotic is, at its core, a chemically measured "version" of a natural antibiotic called teixoblastin, discovered by American researchers in 2015 - it is known that its properties allow it to effectively fight viruses such as MRSA and VRE. Scientists from Lincoln University were able to synthesize a simpler form of this natural antibiotic by working with a change in the location of key amino acids in its structure - thus, they were able to obtain several strains of this antibiotic at once.

Further, their colleagues from the Singapore Eye Research Institute used one of the strains to try to treat some superbug in experimental rats - and they succeeded. But in addition to its primary function of treating and eliminating superbugs, this modified antibiotic also significantly prevents the further growth of such bacteria, creating a special environment in the human body.
