Using light beams for communication is not a new idea, even outside of Star Trek, Star Wars, and other similar fantasy stories. Scientist and science fiction writer Arthur Clark predicted that beam communication, at that time modern satellite communication was just a dream.In 1975, the magazine published an article about laser communication or laser communication equipment. The demonstrati...
Two photon polymerization is a potential method for nanofabrication of integrated nanomaterials based on femtosecond laser technology. The challenges faced in the field of 3D nanoprinting include slow layer by layer printing speed and limited material selection due to laser material interactions.In a new report in Progress in Science, Chenqi Yi and a team of scientists in the fields of technical s...
Figure 1. The setup of Hui Zhao and his team at the University of Kansas Ultra Fast Laser Laboratory.A team of researchers from the University of Kansas's ultrafast laser laboratory recently managed to capture real-time ballistic transmission of electrons in graphene, which could lead to faster, more powerful, and more energy-efficient electronic devices in the future.The motion of electrons is of...
Researchers have developed a new experimental platform that can measure the light wave electric field captured between two mirrors with sub periodic accuracy. This electro-optical Fabry Perot resonant cavity will achieve precise control and observation of the interaction between light and matter, especially in the terahertz (THz) spectral range. The research results were published in the journal "...
Figure: Researchers have created a chip based ring resonator that operates in the ultraviolet and visible light ranges and exhibits record low UV loss. The resonator (small circle in the middle) is displayed as blue light.Researchers have created chip based photonic resonators that can operate in the ultraviolet (UV) and visible regions of the spectrum and exhibit record low UV loss. The ne...
