Silicon Integrated High Speed Electrooptic Modulators

Research
Yale University
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. Wafer-scale deposition of highly oriented metallic films allows CMOS-compatible, monolithic integration of active photonic elements on large scales.

CRISP NanoDays and Yale Pathways

Education
Yale University
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.

Teaching materials science using modern electronics

Education
Yale University

Modern electronics, e.g. a smart phone, relies heavily on science and engineering: semiconductors (diodes, transistors), magnetism (hard drives), photoelectric effect (digital camera), photon generation and lasers (LEDs, CD/DVD drives), light polarization (LCD), etc. The immediacy and applicability makes electronics a great tool for teaching science and technology.

CRISP Professional Development Workshops

Education
Yale University

The goal of CRISP professional development workshops is to improve the quality and diversity of STEM education for science teachers in neighboring urban school districts. CRISP offers inquiry-based workshops which utilize CRISP specialized research facilities to emphasize the interdisciplinary nature of materials science and nanotechnology. Workshops have been offered to more than 100 participants to date.

Creating new devices using oxide materials

Research
Yale University

The unique properties of transition metal oxides allow electrons to be manipulated in new ways. At CRISP, we have created an oxide device that enables a gas of electrons to be expanded or compressed with an applied electric field. The expansion or compression of the gas modulates the speed of moving electrons. The change in the speed of the electrons could be utilized in high speed transistors.
