Microelectronic Substrates for Optoelectronic Packages

lectronic systems with the increased functionality and speed required in today’s advanced applications are placing a performance burden on the interconnection and packaging technologies that standard electrical “wiring” approaches simply cannot support. Engineering staff at APL recognized this trend several years ago, and in a collaborative effort with The Johns Hopkins University Department of...

Fabrication of ZnO nanorods for optoelectronic device applications

Hydroxyl free zinc oxide nanorods have been synthesized by a catalyst free surfactant based one-step solid state reaction process. The powder X-ray diffraction studies reveal well defined wurtzite peaks due to crystalline ZnO, while optical absorption spectra represent prominent exciton absorption and remarkable blueshift in the onset of absorption. As predicted by transmission electron microsc...

CMOS-Based Optoelectronic On-Chip Neural Interface Device

On-chip neural interface devices based on CMOS image sensor technology are proposed and demonstrated. The devices were designed with target applications to optogenetics in bioscience. Multifunctional CMOS image sensors equipped with an addressable on-chip electrode array were integrated with a functional interface chip that contained embedded GaInN light emitting diodes (LEDs) and electrodes to...
