Demonstration of 30-Tbps/cm2 Bandwidth Density by Silicon Optical Interposers Fully Integrated with Optical Components

Bit error rate analysis of a silicon optical interposer using its equivalent circuit

“…4(b) and 4(c). Actually, optical links with more than 20-Gbps [3,4] were demonstrated using PIN-type germanium PDs with bandwidths of 45 GHz [11]. As discussed above, we can predict and optimize the total performance of the optical link from discrete device characteristics using this simulation technique.…”

“…We have previously proposed a photonics-electronics convergence system using a silicon optical interposer to improve the bandwidth bottleneck. We demonstrated a high bandwidth-density of more than 10 Tbps/cm 2 in a silicon optical interposer integrated with an arrayed laser diode, optical modulators, photodiodes, and optical waveguides on a single silicon substrate [2,3]. Furthermore, our optical interposer was verified to be compatible with a high-performance field-programmable gate array (FPGA) [4].…”

High-density silicon optical interposer for inter-chip interconnects

“…We confirmed that the BER was less than 10 -12 when the PD outputs were larger than -5 dBm. The total footprint of the optical components per link channel was 0.0677 mm 2 per channel, meaning we could achieve a bandwidth density of 30 Tbps/cm 2 with a channel line (a) rate of 20 Gbps [8].…”
