“Ultrashort optical pulses are useful for a wide range of applications such as processing materials via strong light-matter interaction. In the frequency domain, a train of pulses represents an equidistant grid of frequency lines, known as an “optical frequency comb …
“Engineers and software developers around the world are seeking to create technology that lets users touch, grasp and manipulate virtual objects, while feeling like they are actually touching something in the real world. Scientists at EPFL and ETH Zurich have …
““We made a major discovery, which questions our understanding of the formation of the first generations of stars in the universe”. Researcher at EPFL Laboratory of astrophysics (LASTRO), Pascale Jablonka is a founding member of the Pristine survey, an international …
“Ultrashort optical pulses are becoming more and more relevant in a number of applications including distance measurement, molecular fingerprinting and ultrafast sampling. Many of these applications rely not only on a single stream of pulses – also known as “optical frequency …
“Over the years, various solutions have been developed to restore tactile information to people with limb amputation. However, this information is still far from those of the human hand in terms of naturalness and effectiveness. The solution to this important …
“Through innovative use of a neural network that mimics image processing by the human brain, a research team reports accurate reconstruction of images transmitted over optical fibers for distances of up to a kilometer. In The Optical Society’s journal …
“EPFL researchers have taught a type of machine learning algorithm to reconstruct images that became blurred while being transmitted through an optical fiber. The work could increase the amount of information transmitted through telecommunications networks, improve endoscopic imaging used in …
“In recent years optical fibers have served as sensors to detect changes in temperature, like a thermometer, and pressure, like an artificial nerve. This technique is particularly useful in structures such as bridges and gas pipelines. EPFL researchers have now …
“In recent years, robotics experts have taken a page from the traditional Japanese practice of origami and come up with light and flexible – and highly innovative – robots and drones. Two types of origami-inspired structures have emerged: rigid structures that have …
“Excitons could revolutionize the way engineers approach electronics. A team of EPFL researchers has created a new type of transistor – one of the components of circuits – using these particles instead of electrons. What is remarkable is that their exciton-based transistor …
