A compact, high-optical-coupling-efficiency transceiver with lens-integrated optical devices and high-capacity 25-Gbps/ch × 12-ch flexible waveguides

A compact optical low-power (9 mW/Gbps) transceiver with lens integrated devices and 12-ch flexible waveguides for optical interconnects was developed. It provides high optical-coupling efficiency and large tolerances (>-2.5 dB and >+/-15 μm) and demonstrated 25-Gbps/ch error-free transmission.
