A 53-Gbit/s VCSEL-Based High Density Optical Assembly for Large Capacity Optical Interconnection

A 53-Gbit/s VCSEL-based compact optical module is proposed. In order to realize 50-Gbit/s-class optical transmission, high-bandwidth optical devices are important. Accordingly, the feasibilities of a high speed optical circuit applying high-bandwidth (>20 GHz) optical devices were studied by simulation. Moreover, an optical module at the receiver (Rx) side was fabricated on the basis of simulation results by applying our developed high density optical assembly techniques, and it successfully demonstrated 53.125-Gbit/s PAM4 multimode optical transmission.
