On-chip optical modulation is one of the most important functionalities for integrated silicon photonic circuits. We demonstrate that sputter-deposited polycrystalline metallic thin films are promising materials for realizing ultra-low power modulators.
On March 22, 2012, CRISP, in collaboration with Yale's Science Pathways, hosted a public lecture in support of the 2012 NanoDays national outreach campaign. IRG2 leader Jan Schroers gave a talk entitled, Strong as Steel, but Pliable as Plastic: Metals Conquering the Nanoworld. Hands-on demonstrations for students were provided by CRISP researchers.
Colloidal silicon quantum dot solution is stable over months
First principles modeling demonstrates that the efficiency of Multi-Exciton Generation (MEG) increases as quantum dot size decreases resolving a major controversy. The results were highly visible.
Polymer gels undergoing a self-oscillating chemical reaction have been previously shown to pulsate autonomously while exhibiting periodic color changes. Van Vliet and Balazs have now demonstrated that a non-oscillating, quiescent gel can be “resuscitated” by applying mechanical pressure to the material. By varying the conditions of the reaction, the amplitude and
MRSEC researchers have developed the materials necessary to embed GHz speed electronic photodetectors into micron diameter channels in optical fibers.
An international team studying the motion of both bacteria and similar-sized artificial catalytic nanomotors has found that they transfer momentum to their surroundings in a similar way, despite their very different propulsion mechanisms.
