➀ Researchers have explored a novel approach to boost thermal transport across solid interfaces by activating hyperbolic phonon-polariton (HPhP) modes in hexagonal boron nitride (hBN).
➁ These hybrid light–vibration modes can transfer energy at rates far exceeding conventional phonon–phonon conduction.
➂ The study shows that hBN can act as a high-performance medium for ultrafast thermal dissipation, with potential applications in high-frequency or high-power devices.
Alphawave Semi is sampling its portfolio of optoelectronics products targeting the high-speed interconnect semiconductor market, expected to exceed $4 billion by 2028. The portfolio includes DSPs for PAM4 and emerging Coherent-lite modulation, using PAM4 SerDes with its WidEye DSP architecture and EyeQ diagnostic technology. The 800G and 1.6T interconnect products support up to 20km optical reach based on PAM4 and Coherent-lite solutions.
➀ Researchers have developed a novel method to enhance the efficiency of perovskite light-emitting diodes (PeLEDs) using polycaprolactone-silver nanoparticles (PCL@AgNPs-P) as an emission gain layer, improving luminance and external quantum efficiency (EQE).
