Extending optical fiber's ultralow loss performance to photonic chips

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new generation of ultra-coherent and efficient photonic integrated circuits (PICs), which will have a profound impact in a variety of on-chip applications, including precision measurements, such as optical clocks for timing and gyroscopes for rotation, as well as AI data-center communications and even quantum computing.

Why reinforcement learning breaks at scale, and how a new method fixes it

From autonomous cars to video games, reinforcement learning (machine learning through interaction with environments) can have an important impact. That may feel especially true, for example, when you're a passenger late for dinner in an autonomous car that has learned the efficient way home. Work in Jr-Shin Li's lab develops mathematically rigorous and computationally efficient techniques to transform extremely complex reinforcement learning problems into a manageable domain.

From trash to takeoff: Pilot plant produces 100 kg of sustainable aviation fuel per day from landfill gas

The aviation industry accounts for a significant share of global carbon emissions. In response, the international community is expanding mandatory use of Sustainable Aviation Fuel (SAF), which is produced from organic waste or biomass and is expected to significantly reduce greenhouse gas emissions compared to conventional fossil-based jet fuel. However, high production costs remain a major challenge, leading some airlines in Europe and Japan to pass SAF-related costs on to consumers.
