A Rainbow of Possibilities

06-21-17

Professor Andrei Faraon, graduate student Ehsan Arbabi, and their colleagues have developed a metasurface or a sheet of material that can be altered on demand to exhibit properties not usually found in natural materials. For example, materials engineered at the nanoscale can control the dispersion of light and could be the basis of next-generation spectrometers and other imaging devices. [Caltech story]

New, Ultrathin Optical Devices Shape Light in Exotic Ways

09-03-15

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, and colleagues have created silicon nanopillars devices capable of manipulating light in ways that are very difficult or impossible to achieve with conventional optical components. The devices are precisely arranged into a honeycomb pattern to create a "metasurface" that can control the paths and properties of passing light waves. Professor Faraon describes, "this new technology is very similar to the one used to print semiconductor chips onto silicon wafers, so you could conceivably manufacture millions of systems such as microscopes or cameras at a time."

New Thin, Flat Lenses Focus Light as Sharply as Curved Lenses

05-08-15

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, and colleagues have created flat microlenses with performance on a par with conventional, curved lenses. Typically, lenses rely on a curved shape to bend and focus light. But in the tight spaces inside consumer electronics and fiber-optic systems, these rounded lenses can take up a lot of room. The Caltech team’s new flat lenses focus as much as 82 percent of infrared light passing through them. By comparison, previous studies have found that metallic flat lenses have efficiencies of only around a few percent. [Caltech story]

Professor Faraon Receives NSF CAREER Award

02-05-15

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his 5-year project, “Quantum Light-Matter Interfaces Based on Rare-Earth Ions and Nanophotonics”. The CAREER program is NSF's most prestigious awards for junior faculty members. The level and 5-year duration of the awards are designed to enable awardees to develop careers as outstanding teacher-scholars. Awardees are chosen because they exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.

Creating New Quantum Building Blocks

02-07-13

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, and colleagues have laid the groundwork for an on-chip optical quantum network by showing that defects in diamond can be used as quantum building blocks that interact with one another via photons. "Right now we only have one nitrogen-vacancy center that's emitting photons, but in the future we envision creating multiple nitrogen-vacancy centers that emit photons on the same chip," Faraon says.

Diving Into the Unknown: An Interview with Andrei Faraon

11-13-12

Assistant Professor and alumnus Andrei Faraon builds devices that are based on the fundamentals of light–matter interaction. He is trying to manipulate single quantum systems in solids—systems like single atoms or single quantum dots—using light. Light is great for this purpose because it allows him to address these systems without destroying their fragile quantum states, and because it can easily interconnect quantum systems over large distances.
