Banks are quietly fortifying private credit deals with sophisticated legal protections as distress signals emerge. J.Crew blockers now appear in 45% of deals, up from just 15% in 2023, signaling lender anxiety about coming defaults.
Scientists have identified and eliminated copper contamination as the primary thermal absorption source in silicon nitride photonic circuits. This breakthrough enables deterministic generation of dissipative Kerr solitons, overcoming a major hurdle in chip-scale optical frequency comb technology.
Researchers have made a significant breakthrough in integrated photonics by identifying copper impurities as the primary source of thermal absorption in silicon nitride photonic integrated circuits (PICs), according to a recent study published in Nature. Sources indicate that these impurities, previously undetected in electronic-grade silicon wafers, were found to diffuse into the silicon nitride layer during high-temperature annealing processes and become trapped, creating thermal effects that have hampered deterministic soliton generation.

A Minnesota startup is developing revolutionary laser cooling technology that converts heat directly into light. The approach could eliminate dark silicon limitations and dramatically improve chip performance while reducing energy consumption.
According to reports from Minnesota-based startup Maxwell Labs, researchers are developing a groundbreaking technology that uses lasers to cool high-performance chips by converting heat directly into light. This approach, reportedly called photonic cooling, represents a fundamental shift from traditional cooling methods that simply move heat away from chip surfaces. Sources indicate this technology could potentially cool hot spots with power densities orders of magnitude higher than current chips can handle.
