Millimeter-wave wireless interconnects is an emerging technology for ultra-short-reach off-chip transmission, providing
spatial flexibility and power-efficient high-speed data transportation. Integrated with carrier-over-fiber technology, we
propose a low-phase-noise multi-wireless-transceiver architecture to improve the bit-error-rate performance of
conventional wireless interconnects. Multiplexing schemes, including frequency division multiplexing, spatial
multiplexing, and beam isolation, can be facilitated by carrier-over-fiber techniques. We introduce a potential application
of the multi-input-multi-output high-speed analog multiplexing with open-loop analog circuits and digital feedback.
We proposed a novel optical coupling technology for short-reach interconnection (<10m) on flexible polymer
waveguides. In order to decrease time and cost of fabrication and assembly, edge-emitting lasers and edge-viewing
photodetectors are embedded directly into flexible polymer waveguide in a parallel lithography process. This avoids
lenses or angle-reflected components, such as 45° mirrors or volume gratings, which are widely used for VCSEL
coupling. Multi-channel optical interconnection can be implemented by passive alignment in a one-time optical
lithography process, and no additional expensive components are needed to achieve high coupling efficiency.
