Key Technology Manufacturing Areas (KTMA)
Initiative focuses on the challenges for manufacturing high volume, low cost Terabit-scale photonic interconnectivity technology for advanced high performance embedded computing and data centers.
Initially focus is on ultra-high-speed, high quality multi-wavelength communications links exceeding TB/s bandwidth densities; and multi-port (high-radix) spatial and wavelength selective, nanosecond-scale reconfigurable switches.
RF Analog Applications
Initiative objective is to develop manufacturing technologies specifically targeted for producing high volume chip-scale microwave photonics for demanding applications requiring very high optical performance fidelity. The driving goal is to address the critical challenges for the mass manufacture capable integration of high-dynamic range ultra-low loss broadband PICs and microwave frequency electronic ICs for unprecedented analog RF transmission communication performance.
Initiative addresses the manufacturing challenges of chemical and biochemical sensors realized in glass/silicon materials, and demonstrates how the proposed solutions can facilitate high-volume production of embedded sensors connecting to or integrated with mobile platforms. Goals include development and demonstration of manufacturing methods enabling dramatic miniaturization of sensor systems based on glass/silicon integrated photonics and novel engineered glass surfaces
PIC Array Technologies
Initiative addresses the manufacturing challenges associated with PIC Phased Arrays. The primary focus of this effort will be on chi based LIDAR. Phased arrays enable high-speed steered projection and imaging without moving parts. Applications extend to Light Distance and And Ranging (LIDAR); Biomedical Imaging; Free-Space Communications; and Display Technologies.
