Silicon Bench for Passive Coupling and Packaging of High-Frequency Optoelectronic Devices

Coupling and packaging have become decisive factors in the final performance and cost of high-frequency optoelectronic devices. Here, we report the design and successful fabrication of a silicon bench that integrates a V-groove and high-frequency coplanar waveguide (CPW) on the same high-resistivity silicon wafer as an effective optoelectronic packaging solution
