Recently, the transit service by automobiles and railways are evolving. On the other hand, the development of the transmit service by vessels is delayed compared to automobiles and railways system. Therefore, we have started the development of the operation support system for water transit service capable of remote operation, monitor and autonomous navigation. It can be expected the reduction of maritime...
We demonstrated athermal silicon optical interposers integrated with quantum dot lasers at 1.3 μm, achieving a bandwidth density of 15 Tbps/cm2 with a channel line rate of 12.5 Gbps operating up to 125 °C without any bias adjustment.
We demonstrated a 25-Gbps error-free data link on a silicon optical interposer. The experimental results verified that our interposer is compatible with high-performance FPGAs, and transmitter pre-emphasis and receiver equalization reduced bit error rate of the optical data link.
Silicon optical interposers for inter-chip interconnects, integrated with lasers, optical splitters, modulators, waveguides and photodetectors on a single silicon substrate were demonstrated. They were optically complete and closed systems. We achieved 20-Gbps error-free data transmission and a 30-Tbps/cm2 bandwidth density using these interposers.
Silicon optical interposers for inter-chip interconnects, integrated with an arrayed laser diode, an optical splitter, silicon optical modulators and germanium photodetectors on a single silicon substrate were demonstrated. A 12.5-Gbps error-free data transmission and 6.6-Tbps/cm2 transmission density were achieved.
A 64-year-old Japanese female, diagnosed as dermatomyositis with acute interstitial pneumonia, complained of acute abdominal pain. Computed tomography of the abdomen showed hematoma in the right retroperitoneum and left rectus-sheath. Angiogram showed multiple small aneurysms on left iliolumbar artery and a horizontal linear flush, suggesting active bleeding foci in the muscles. Although arterial...
