It is well-known that interconnect issues pose a significant bottleneck with regard to improving the performance of high-speed integrated systems such as a cluster of computer processing units. Power, speed (bandwidth), and size all affect the computational performance and capabilities of future systems. High speed optical processing has been looked to as a means for eliminating this interconnect bottleneck. Presented here are the results of a study for a novel ...
This research plans to develop enhanced contrast thermal acoustic imaging (TAI) technology for the detection of breast cancer by combining amplitude-modulated (AM) electromagnetic (EM) field excitation resonant acoustic scattering and advanced signal processing techniques. While EM-induced TAI possesses great promise, the thermal acoustic signals tend to be weak However when the tumor is excited into resonance via EM stimulation the effective acoustic scattering cross-section may increase by a factor in ...
An electro-absorption modulator (EAM) is designed to optimize dynamic range performance over 20 GHz bandwidth. The single stripe waveguide enables an extremely compact and integrated package to be fabricated with single mode fiber pigtails. The transfer function's shape permits suppression of higher order intermodulation products, yielding a spur-free dynamic range exceeding that of Mach-Zehnder designs. A dilute optical core diverts energy flow from absorbing layers into a low loss waveguide; ...
