This breakthrough research from Shanghai Jiao Tong University overcomes critical barriers to silicon micro-ring resonator (MRR) commercialization. By heterogeneously integrating low-loss phase-change material Sb₂Se₃, the team created non-volatile, "smart-programmable" transceivers enabling precise, full-spectral-range wavelength tuning via electrical pulses. Crucially, the technique preserves high performance, achieving 100 Gbps per MRR (400 Gbps total for 4 cascaded rings) and introducing an innovative thermal compensation scheme for stability. This work provides a robust solution for high-density, low-power optical interconnects, accelerating MRR technology from the lab towards transformative applications in data centers and high-speed networks, while showcasing the power of multidisciplinary innovation.
Research on the optical coherence manipulation has made significant progress, but the modulation rate of conventional tailoring technology is too low, which has become a key factor hindering its transition from laboratory to practical application. Here, we utilize lithium niobate films (LNF) modulator to achieve high-speed optical coherence manipulation based on its high-speed electro-optical modulation capability. Our experimental modulation rate reaches 350 kHz, which is about 20 times higher than the fastest modulation rate reported so far. This design strategy provides a simple rule for high-speed optical coherence manipulation based on electro-optical modulation, paving the way for further practical applications of optical coherence manipulation technology.
Researchers from the University of Münster have succeeded for the first time in using spin-polarised scanning tunnelling microscopy to image structural and magnetic properties that lie beneath the surface of a layered system of 2D graphene and iron
Extreme environments demand smarter sensors! A team from Zhejiang University has developed a laser-induced, in-situ fabrication method for thin-film temperature sensors with no complex layering, no extra coatings.
