Lithography is one of the core processes in semiconductor manufacturing, and extreme ultraviolet lithography technology, as a new generation lithography technology, is also in a rapid development stage. The basic principle is to use photoresist (also known as photoresist) to form corrosion resistance due to photochemical reactions after being photosensitive, and to engrave the patterns on the mask...
Recently, Coherent, an American laser system solution provider, announced that all of the company's ultra fast laser business, including the manufacturing of all picosecond and femtosecond lasers, will be unified in one place: the Ultra Fast Center of Excellence in Glasgow, Scotland.Previously, Coherent's Ultra Fast Center of Excellence located in Glasgow was already a state-of-the-art mass produc...
At present, the navigation system has become an important equipment on ships, aircraft, missiles, automobiles and other navigational vehicles. Laser Doppler radar has become an important development direction in the field of velocity measurement technology because of its high accuracy, good spatial resolution and fast dynamic response. The application of the three-beam Doppler Lidar in the...
Recently, Fujitsu and KDDI research company have successfully developed a high-capacity multi band wavelength multiplexing transmission technology using installed optical fibers.The new technology of the two companies can transmit wavelengths beyond the C-band by using batch wavelength conversion and multi band amplification technology.Expanding transmission capacity in remote areasTwo companies h...
Researchers at Busan National University, led by Kwangseuk Kyhm, Professor of Ultra Fast Quantum Optoelectronics from the Department of Optics and Mechatronics, are enhancing signal amplification inside cesium bromide lead perovskite nanosheets through patterned waveguides.Perovskite is a highly attractive material in solar cell applications, but its nanostructure is now being explored as a new la...
