Faculty
Abbas El Gamal: Professor of Electrical Engineering
Professor El Gamal’s research group performs research in imaging architectures and algorithms that exploits recent developments in submicron CMOS image sensor technologies and the emergence of 3D integration. Current projects are aimed at achieving high dynamic range and high speed imaging system-on-chip for industrial and tactical applications, ultra high sensitivity lab-on-chips for biological testing applications, and algorithms for collaborative computing over imaging sensor networks. High dynamic range is achieved by using CMOS technology scaling to integrate A/D conversion at each pixel, enabling ultra high speed readout.
Shanhui Fan: Assistant Professor of Electrical Engineering
Professor Fan’s group performs research on the theory and simulation of photonic solid state materials and devices for telecom and information technology applications. Particular areas of interest include photonic bandgap materials, nanoscale photonic devices and metamaterials. The Fan group is exploring the use of dynamic photonic structures for the storage of light for data buffering applications and modeling magneto-optic materials for storage applications. Dr. Fan’s group has collaborated with the Solgaard group on tunable filters based upon photonic bandgap crystals. In collaboration with the Kahn group, they are exploring the use of adaptive optics to achieve high data rate transmission in multi-mode fibers. Dr. Fan’s group is also exploring the use of dynamic photonic structures for stopping, storage, and time reversal of light for packet buffering in all optical switches.
Michael Fayer: David Mulvane Ehrsam and Edward Curtis Franklin Professor of Chemistry
Dynamics and intermolecular interactions of molecules in liquids, liquids in nanoscopic environments, room temperature ionic organic liquids, supercooled liquids, and liquid crystals.
Robert Feigelson: Professor of Materials Science and Engineering, Emeritus
Nonlinear optical materials
James Harris: Professor of Electrical Engineering
Professor Harris’s group does research on the growth, characterization, nanofabrication and device implementation of unique compound semiconductor materials. Harris’s group has pioneered the development of low bandgap GaInNAsSb materials for efficient long wavelength telecom lasers on GaAs substrates. His group also uses carefully controlled molecular beam epitaxy combined with nanolithography to prepare artificially structured materials with atomic layer control and enhanced performance. Recent achievements include new materials that extend the wavelength range that can be covered by VCSELs on GaAs substrates and, in collaboration with Miller’s group, new quantum well materials for high performance electro-absorption modulators that are compatible with Si substrates.
Lambertus Hesselink: Professor of Electrical Engineering
Professor Hesselink’s group focuses its research on fundamental processes related to laser-matter interaction with novel applications in telecom technology. Hesselink’s group is investigating fundamental materials processes in electro-optic media for manipulation of the index of refraction and modification of the interaction between waves and grating structures for WDM switching applications. They have also pioneered the development of digital holographic data storage systems. Currently, Dr. Hesselink’s group is exploring ultra dense optical storage on phase change and magneto-optic materials using near field recording through efficient nano-sized apertures.
Joseph Kahn: Professor of Electrical Engineering
Professor Kahn’s group is focused on optical fiber communications, free-space optical communications and associated devices/subsystems. Of particular interest are advanced modulation, coding and detection for high spectral efficiency and enhanced tolerance to transmission impairments, as well as signal processing to compensate these impairments. In free-space systems, Kahn’s group is working with Prof. Fejer’s group on wavelength converters to enable mid-IR transmission, and on signal processing to compensate for atmospheric turbulence. Professor Kahn’s group also does research on high data rate transmission in multi-mode fibers. In collaboration with Dr. Fan’s group, Kahn’s group has used adaptive optics to mitigate modal dispersion to increase the distance over which signals can be transmitted at high bit rates and have demonstrated 10 Gbps transmission over more that 10 km of standard multi-mode fiber.
Mark Kasevich: Professor of Physics and Applied Physics
High accuracy navigation and gravimetric sensors based on de Broglie wave interferometry; Future atom optics sensors which exploit the novel coherence properties of Bose-Einstein condensates
Marc Levoy: Professor of Computer Science and Electrical Engineering
Professor Levoy’s group is currently performing research on light field imaging and display, computational imaging, and digital photography.
His group has built optoelectronic devices for measuring 3D shape, light fields and reflectance functions. These include a real-time range scanner based on video projectors, a handheld camera for capturing instantaneous light fields, and a multi-camera array for acquiring video light fields. A light field is a 2D array of 2D images, each taken from a different viewpoint. By assembling pixels from several images taken from different viewpoints, new views can be constructed from observer positions not present in the original array.
Liqun Luo: Biological Sciences and Neurobiology
Liqun Luo seeks to understand how neural circuits assemble during development and contribute to sensory perception. He has developed the MARCM technique to track neurons in the fruit fly brain and is perfecting a similar system for studying mice.
