dual-helix CT enables large objects up to 20 in. (50 cm) in height and 12 in. (30 cm) in diameter to be scanned. Ade- quate contrasting can become a problem, especially when it comes to the resolution of structures in low-contrast soft tissue, such as organs, mus- cles and fat cells. A central task of the museum will be to find solutions and process optimiza- tion using contrast media, while as- sisting YXLON with the correspon- ding refinement of the CT system and its software.

cladding so unique is anisotropy, meaning that the cladding design en- ables light to travel at different ve- locities in different directions. By controlling the anisotropy of the cladding, the researchers prevented light from leaking off track into other waveguides where “crosstalk,” or mixing, of information would occur. Instead, bits of information carried by light bounce off by “total internal reflection” and stay strongly confined within a waveguide. Ultra-compact, densely inte-

grated optical components manufac- tured on a CMOS-foundry platform are highly desirable for optical infor- mation processing and electronic- photonic co-integration. However, the large spatial extent of evanescent waves arising from nanoscale con- finement, like that found in silicon photonic devices, causes significant crosstalk and scattering loss. The team’s findings, published


in Nature Communications, show a reduction of crosstalk greater than 30 times and bending loss more than three times, in densely integrated, ul- tra-compact photonic circuit blocks. The prototype all-dielectric

metamaterial waveguide achieves very low propagation loss, compara- ble to that of silicon strip wave- guides. This approach marks a de- parture from interference-based con- finement as in photonic crystals or slot waveguides, which use nano - scale field enhancement.


“The waveguide we made is an


extreme skin-depth structure, which means that any leakage that does happen will be really small,” says Saman Jahani, Purdue graduate re- search assistant in electrical and computer engineering. “This ap- proach can pave the way for dense photonic integration on a computer chip without worrying about light leakage.” Web: www.purdue.edu r

proving the efficiency and flexibility of the system. Computers with these new


blocks, which the researchers call “memory-processing units,” could be particularly useful for implementing machine learning and artificial intel- ligence algorithms. They are also well-suited to tasks that are based on matrix operations, such as simula- tions used for weather prediction. Lu’s team chose to solve partial


differential equations as a test for a 32 x 32 memristor array, which Lu imagines as just one block of a future system. These equations, including those behind weather forecasting, underpin many problems in science and engineering but are very chal- lenging to solve. The difficulty comes from the complicated forms and mul- tiple variables needed to model phys- ical phenomena. When solving partial differen-


tial equations exactly is impossible, solving them approximately can re- quire supercomputers. These prob- lems often involve very large matri- ces of data, so the memory-proces- sor communication bottleneck is neatly solved with a memristor ar- ray. The equations Lu’s team used in their demonstration simulated a plasma reactor, such as those used for integrated circuit fabrication. Web: www.umich.edu r
