Tens of terabits-per-second bandwidth will be required for revolutionary chip-multithreading (CMT) architectures. In this presentation, we will review the technical challenges for electrical signaling and discuss how parallel optical interconnects could be valuable in CMT architectures.

We have made a thin flexible waveguide film for fully embedded board level optical interconnections. First, the master waveguide structures are formed on a silicon wafer using a standard photolithography process. Two 12-channel, 850 nm VCSEL arrays (2.5 Gb/s and 10 Gb/s) and a PIN photodiode array are used as I/O sources on a flexible polymeric waveguide film. The initial substrate thickness (200 /spl mu/m) of the VCSEL is reduced to facilitate thermal management of the VCSEL and the fully embedded structure.

We report a label-free biosensor system that consists of a tunable VCSEL, a plastic guided mode resonant filter and two pin detectors. The biosensor has'demonstrated the sensitivity of detecting antigen proteins concentration as low as Ipg/ml (6.7fM) and antibodies to dengue virus.

Microring resonators constitute ideal microspots where the target reaction are spatially confined and exhibit high signal density. These devices have very high quality factors, Q up to 10/sup 8/ which translates to enhanced sensitivity and signal-to-noise ratio. The combination of high Q and small geometry leads to significant power buildup within the microcavity and can allow the accurate detection of very few molecular events on the ring surface. We have designed and fabricated devices with different geometries and optimized operational wavelength ranges. In addition to high volume microfabrication, Hydex/sup /spl trade// allots us to functionalize the ring using established immobilization protocols for antibodies, nucleic acids, receptors and artificial sensing layers. Preliminary testing used the well documented and versatile biotin-avidin complex to immobilize an antibody biofilm. With Hydex/sup /spl trade// we can design highly-sensitive, readily portable label-free and reagent-free assays.

Biliproteins represent a diverse class of highly pigmented proteins that utilize light energy throughout the visible and near infrared (NIR) region of the light spectrum. By exploiting and/or genetically altering the double bond regiospecificity of the ferredoxin-dependent bilin reductases, in combination with (semi)synthesis of novel linear tetrapyrrole precursors and directed evolution of apophytochrome genes, we seek to develop new-biliprotein reagents with novel chemical proteins and biochemical functions. Among the target applications of our studies include: NIR emitting fluorescent proteins, gene-based fluorescent labels, light-regulated gene expression delivery systems, designer biliproteins, and FRET-based approaches to study protein-protein interactions.
