    ABSTRACT: Digital signal processing concepts have been successfully taught in the lower division for the past ten years and now have been introduced into an engineering course designed for juniors and seniors in high school. This hands-on curriculum allows students to do real time audio, video, and communication projects using a board similar to a Texas Instruments DSK and a block diagram based development tool. The infinity curriculum, supported with a text book using precalculus mathematics, allows students to gain experience with basic concepts of DSP that they will study later with more rigor if they choose to major in engineering. The course has been adopted by over eighty high schools and has been taught in some high schools for three years.

    ABSTRACT: We describe flip chip bonding of arrayed optoelectronic devices (VCSELs, MSM and PIN detectors) onto ultra-thin silicon-on-sapphire (UTSi). We present results of UTSi optical transmitters and receivers for 2.5 Gbps (and higher) parallel optical links.

    ABSTRACT: A bold new plan has been initiated to bring state-of-the-art science-based technology and engineering education to high schools. This effort, called The INFINITY Project, aims to develop a novel and interactive curriculum emphasizing the engineering fundamentals and the fun of the modern high-tech age. This course isn't about “surfing the web”-rather, it teaches students about the science and engineering which enable the web. This course doesn't focus on how to use email to reach friends and family-rather, it teaches the physics and modern engineering which have given rise to cellphones and high speed digital networks. This course does not focus on how to use computers to play video games or DVD players to watch high resolution digital videos-rather, it focuses on the basic mathematics, and algorithms which enable these devices to entertain us and enrich our lives

    ABSTRACT: The technology of vertical-cavity surface-emitting lasers (VCSELs) as used in optoelectronic interconnects is becoming quite mature and is finding many fiber and free-space interconnect applications. The 850-nm GaAs-AlGaAs quantum well VCSEL technology is the most mature and most widely employed for fiber interconnects. Unfortunately, flip-chip bonded 850-nm VCSELs are sandwiched between the opaque complementary metal oxide semiconductor (CMOS) silicon and optoelectronic GaAs substrates, requiring GaAs substrate removal or some other additional measures to achieve successful interconnects. We discuss new Si-on-sapphire CMOS applications
