Single-Fiber Bidirectional Optical Data Links with  Monolithic Transceiver Chips

<table>Photograph of a transceiver chip consisting of a VCSEL and a PIN photodiode, each with indicated ground-signal-ground (GSG) microwave probe contacts. The VCSEL is positioned off-center with respect to the photodetector in order to maximize the effective photodetecting area of the transceiver. The dashed circle indicates the alignment of a MMF with 50 <i>μ</i>m core diameter (from [<a href="/journals/aot/2012/729731/#B21">20</a>]).</table>
