Scientists have discovered that removing trace copper ions from photonic integrated circuits enables perfect generation of optical frequency combs. This breakthrough addresses thermal instability issues that have hampered chip-scale photonic applications for decades.
Researchers have demonstrated that eliminating microscopic copper contamination from photonic integrated circuits enables reliable generation of sophisticated light spectra, according to a recent study published in Nature. The findings, reportedly from Ji and colleagues, reveal that even trace amounts of copper ions—previously considered negligible—can severely degrade the performance of optical microchips used in communications and sensing applications.
A Minnesota-based startup is developing a revolutionary approach to chip cooling using laser technology. The system converts heat directly into light, targeting hot spots with precision that could eliminate current thermal limitations.
A groundbreaking approach to chip cooling that uses lasers to convert heat into light is being developed by Minnesota-based startup Maxwell Labs, according to reports. The technology, called photonic cooling, represents a fundamental shift from traditional cooling methods that simply move heat away from chips. Sources indicate this could potentially solve the persistent problem of dark silicon, where up to 80% of transistors on modern chips must remain inactive to prevent overheating.
