This week in the VINSE Spotlight Podcast Kent Hallman tells Alice Leach about using VO2, a phase change material, to build photonic devices. Kent’s paper “Sub-Picosecond Response Time of a Hybrid VO2 :Silicon Waveguide at 1550 nm” was published in Advanced Optical Materials.  Kent graduated with a Ph.D. Read More

by Marissa Shapiro Jan. 14, 2021, 1:05 PM Vanderbilt researchers have developed the next generation of ultrafast data transmission that may make it possible to make already high-performance computing “on demand.” The technology unjams bottlenecks in data streams using a hybrid silicon-vanadium dioxide waveguide that can turn light… Read More

In Episode 32 of the VINSE Spotlight Podcast Kannatassen ‘Krishen’ Appavoo tells Alice Leach about the phase change material, vanadium dioxide. Typically an insulator, when given a small amount of energy, it becomes conducting and has applications in next generation electronic devices. Krishen’s paper “Doping-driven electronic and lattice… Read More

Take gold spirals about the size of a dime…and shrink them down about six million times. The result is the world’s smallest continuous spirals: “nano-spirals” with unique optical properties that would be almost impossible to counterfeit if they were added to identity cards, currency and other important objects. Students and… Read More

(Joe Howell / Vanderbilt) An ultra-fast and ultra-small optical switch has been invented that could advance the day when photons replace electrons in the innards of consumer… Read More

Twelve Vanderbilt University faculty members were honored for extraordinary contributions to their respective fields during an Aug. 28 celebration of endowed chair holders at the Student Life Center. Jeff Balser, vice chancellor for health affairs and dean of the School of Medicine, noted during his opening remarks the… Read More

Vanadium dioxide crystal lattice (A. Julia Stähler / Fritz Haber Institute) An international team of physicists has developed a method for taking ultrafast “sonograms” that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical… Read More
