The chip-level 1 × 2 optical interconnects using the polymer vertical splitter developed on a silicon Handstick Vacuum Cleaners substrate are demonstrated.The 1 × 2 vertical-splitting configuration is realized using a polymer waveguide terminated at three silicon 45 ° reflectors.The high-frequency transmission lines combined with the indium solder bumps are developed to flip-chip assemble a vertical-cavity surface-emitting laser chip at the input port and two photodetector chips at two output ports.
Total transmission loss of -3.26 dB with a splitting ratio of 1 : 1 for the proposed splitter TV is experimentally obtained.A 10-Gbit/s data transmission with bit error rates better than 10-12 for two output ports is achieved.
It reveals that such chip-level 1 × 2 optical interconnects using the polymer vertical splitter are suitable for high-speed data transmission with multiple output ports.
