Characteristics of Amplifier-integrated 40 Gbps Optical Receiver and Transmitter Modules

We developed amplifier-integrated 40 Gbps optical receiver and transmitter module. The packaging technologies for the high-speed optical module are discussed and applied to develop the modules. For the optical receiver, the design and 40 Gbps NRZ eye diagrams are reported. For the optical transmitter, the manufacturability of wedge bonding to suppress the high-frequency resonance was investigated, and the electrical-to-optical (E/O) response of the module was measured.
