Interferometer on chip Researchers at the University of Rochester developed an optical interferometer on a 2mm by 2mm integrated photonic chip that is capable of amplifying interferometric signals without a corresponding increase in extraneous noise. Interferometers merge two or more sources of light to create interference patterns that provide information able what they illuminate. “If y... » read more

Research is expanding across a variety of semiconductor-related topics, from security to flexible substrates and chiplets. Unlike in the past, when work was confined to some of the largest universities, that research work is now being spread across a much broader spectrum of schools on a global basic, including joint research involving schools whose names rarely appeared together. Among the ... » read more

Optical signal processing with acoustic waves Researchers from Pohang University of Science & Technology (POSTECH) demonstrated an optical-wave signal that can be amplified or canceled using optically driven acoustic waves on a silicon chip. Optical signal processing using Brillouin scattering, in which acoustic waves scatter light, has been demonstrated in nanophotonic structures. But ... » read more

Large-scale phased array Researchers at Princeton University developed a large-scale high-frequency antenna array using thin-film materials. “To achieve these large dimensions, people have tried discrete integration of hundreds of little microchips. But that’s not practical — it’s not low-cost, it’s not reliable, it’s not scalable on a wireless systems level,” said senior stud... » read more

Strong plastics The Massachusetts Institute of Technology has developed a new material that is stronger than steel but is light as plastic. The new material, which can be made in large quantities, involves a two-dimensional polymer that self-assembles into sheets. The material’s Young modulus—or a measure of how much force it takes to deform a material—is between four and six times gr... » read more
