applications such as digital and neural computing, data mining, and data communication
switching, there is a critical need to provide local electronic processing in each
optoelectronic element. Moreover, to achieve the required functionality in these systems,
highly sophisticated devices with state-of-the-art performance are necessary. Thus, large
numbers of densely packed high performance devices originating from disparate
technologies are needed to achieve the next generation of information processing,
interconnect, and intelligent sensing microsystems.
This project produced a number of first-ever research prototypes. The hybrid integration
work was the first demonstration of GaAs drivers and receivers integrated with VCSELs
for spatially multiplexed multi-channel high-speed data links. The flip-chip integration
was the first demonstration of flip-chipped 850 nm VCSELs onto GaAs drivers showing
the possibility of using such arrays under the current short distance datacom standards.
The matrix addressable array work demonstrated the largest number of lasers and
detectors ever integrated onto a single chip, opening the way for scannerless VCSEL
based imaging systems. Fiber image guides show great promise for use in short range
highly parallel array-to-array data transmission compatible with the current 850 nm
datacom standards. Lastly, integration of VCSELs with high performance heat sinks
shows potential for even higher device performance in the future.
