Smaller, cheaper integrated photonics Researchers from the University of California Santa Barbara, California Institute of Technology (Caltech), and Ecole Polytechnique Fédérale de Lausanne (EPFL) developed a way to integrate an optical frequency comb on a silicon photonic chip. Optical frequency combs are collections of equally spaced frequencies of laser light (so called because when pl... » read more

Cooling sensors with lasers Researchers at the University of Washington developed a way to cool a solid semiconductor sensor component with an infrared laser. The laser was able to cool the solid semiconductor by at least 20 degrees C, or 36 F, below room temperature. The device uses a cantilever, similar to a diving board, that can oscillate in response to thermal energy at room temperatur... » read more

AI architecture optimization Researchers at Rice University, Stanford University, University of California Santa Barbara, and Texas A&M University proposed two complementary methods for optimizing data-centric processing. The first, called TIMELY, is an architecture developed for “processing-in-memory” (PIM). A promising PIM platform is resistive random access memory, or ReRAM. Whil... » read more

Flexible, hole-filled films Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) and Hongik University propose a simple way to make flexible electrodes and thin film transistors last longer: adding lots of tiny holes. A major problem with flexible electronics is the formation of microscopic cracks after repeated bending which can cause the device to lose its conducti... » read more

Assessing code similarity Researchers from Intel, MIT, and Georgia Institute of Technology created an automated engine designed to learn what a piece of software intends to do by studying the structure of the code and analyzing syntactic differences of other code with similar behavior. The machine inferred code similarity (MISIM) program, a subset of Intel's work on machine programming, was... » read more

Programmable photonics Researchers from the University of Southampton developed a method for making programmable  integrated switching units on a silicon photonics chip. By using a generic optical circuit that can be fabricated in bulk then later programmed for specific applications, the team hopes to reduce production costs. "Silicon photonics is capable of integrating optical devices and... » read more
