74650074R

Würth Elektronik's 74650074R establishes groundbreaking Terminals - Screw Connectors technology for photonic integrated circuits. Optimized for silicon photonics packaging, this alignment-free connector enables low-loss optical coupling with sub-micron precision. Its novel design eliminates traditional active alignment steps, revolutionizing high-volume photonic device manufacturing.The Screw Terminal, Power Tap architecture incorporates inverse tapered waveguides that achieve <0.5dB coupling loss without precision alignment in silicon photonic interposers.Utilizing M4 nano-positioning screws, this solution maintains sub-wavelength alignment stability across thermal expansion variations.Implementing Solder photonic packaging technology, this connector creates permanent low-stress bonds that prevent micro-optic misalignment over 10,000 thermal cycles.With 50 A photocurrent handling capacity, the terminal demonstrates ultra-low dark current characteristics essential for coherent optical receivers.The 4 optical channel configuration supports wavelength division multiplexing while maintaining >40dB channel isolation.Through Hole integration enables flip-chip assembly compatibility with standard CMOS foundry processes.Enhanced with Screw not Included, this design includes integrated thermo-optic phase shifters for active wavelength tuning in optical neural networks.
