- High power terahertz radiation sources developed by Professor Jarrahi’s group are highlighted in the Laser Focus World Magazine
Work by Professor Mona Jarrahi’s research group on plasmonic photomixers has been highlighted in the Laser Focus World Magazine.
The team has demonstrated a high-performance source of continuous-wave terahertz radiation that can generate record-high radiation powers with extreme frequency tunability, while operating at room temperature.
This has been achieved by incorporating plasmonic nanostructures into a photomixer to offer significantly higher quantum efficiencies than that of previously demonstrated devices. Moreover, this device is designed to operate at standard telecommunication optical wavelengths, which can be incorporated into a relatively compact and inexpensive setup.
The principal investigator on the research is Professor Mona Jarrahi and other authors include Christopher Berry, a former student of Jarrahi’s at the University of Michigan, Ann Arbor; Mohammad R. Hashemi, a UCLA post-doctoral scholar; Sascha Preu, Professor of Electrical Engineering and Information Technology at the Technical University of Darmstadt (Germany); Hong Lu, a researcher at UC Santa Barbara; and Arthur C. Gossard, Professor of Materials, Electrical and Computer Engineering at UC Santa Barbara.

- Asael Papour is Awarded the Dr. Ursula Mandel Scholarship
Asael Papour, a graduate student under the mentorship of Prof. Oscar Stafsudd, received the UCLA Dr. Ursula Mandel Scholarship for scholastic and research achievements in the medical field. Papour has developed two compact biomedical imaging systems using auto-fluorescence and Raman techniques for intraoperative real-time tissue characterization. These robust technologies can image various tissue abnormalities including cancer tumor margins and serve as an early detection system for bone growth (Heterotopic Ossification) in failed wounds (combat wounds). A paradigm change in fluorescence and Raman optical tissue characterization enabled new research approaches, and removed the hurdles for accepting these technologies in patient care. By using spectroscopy-free fast Raman imaging and auto-fluorescence pulse shaping breakthrough, an unmet clinical need for inexpensive, non-ionizing (x-ray) imaging device is created.
Asael is a member of the Quantum Electronics Laboratory under the supervision of Professor Oscar Stafsudd (Electrical Engineering), and Professor Warren Grundfest (Bioengineering/Electrical Engineering). Asael completed a master’s degree in Electrical Engineering from UCLA in 2012. He received bachelor’s degree in Physics, minor in Chemistry, in 2008 from the Hebrew University of Jerusalem, Israel.

- UCLA Researchers Receive $1.29M NSF Grant for Scalable Nanomanufacturing
A team of UCLA researchers has received a $1.29 million, four-year grant from the National Science Foundation to explore low-cost methods of manufacturing fibers with unprecedented continuous metal nanowires — a material with potential for ultra high-resolution cellular electrophysiology analysis technologies that could conduct sub-cellular and intracellular measurements down to a single biological cell.
The principal investigators of the research team include Xiaochun Li, Raytheon Professor of Manufacturing and Chi On Chui, associate professor of electrical engineering and bioengineering, both of the UCLA Henry Samueli School of Engineering and Applied Science; and Huan Meng, an adjunct assistant professor of nanomedicine at the UCLA David Geffen School of Medicine.
While there is a great demand for the high-volume production of fibers with continuous metallic nanowires, there has not been a reliable and scalable manufacturing method due to fundamental and technical issues surrounding their nanoscale size. This includes instability of molten metals during thermal drawing of the wires, and difficulties controlling wire formation using traditional manufacturing techniques. The UCLA research team will explore novel approaches to address these barriers to a low-cost, reliable and scalable nanomanufacturing process.
Current cellular electrophysiology analyses are used in high-volume, such as the development of pharmaceuticals, toxicity screenings, and threat detection. Using fibers with continuous nanowires as narrow as just tens of nanometers in diameter would enable high resolution analytical platforms, which could examine a single to few biological cells at a time. The resultant platforms could measure cellular events that, for example, indicate the presence of cancer cells, earlier than current technologies can. Specifically, the researchers and their students will explore theoretical materials and functional designs for nanoelectrode arrays; scalable nanomanufacturing of fibers with metal nanowires through thermal drawing; observation and characterization of nanoelectrode arrays; and development and validation of nanoelectrode-enabled cell-based assay platforms.
Other potential technologies for this include high-resolution semiconductors and metamaterials characterizations, and neural and cardiac electrical signal recorders.

- UC Engineers Collaborate on Light Emitting Semiconductor on Silicon Using Graphene
Light-generating semiconductor on silicon is the technology with the greatest potential toward integrating electronic and photonic devices on the same chip. Integration of highly-efficient optical sources on silicon will enable the combination of photonics with silicon electronics, leading to many new capabilities, such as providing high bandwidth in optical interconnects, long-haul communication systems and conventional CMOS technology.UCLA Engineering researchers, in collaboration with colleagues at UC Irvine and UC Riverside, have developed a new growth technique using a wonder material, graphene, made from a single layer of carbon atoms, in which electrons travel at incredible speeds. According to this innovation, ultra-smooth light-emitting semiconductor thin films can be deposited successfully on top of the growth-assisting graphene layer which sits on silicon substrate. Led by Kang Wang, the Raytheon Professor of Electrical Engineering at UCLA and the study's principal investigator, the team demonstrated for the first time that the likely-epitaxial light-emitting (i.e. GaAs) thin films can be deposited on silicon using graphene as a buffer layer. The research was published on Aug. 26, 2014, in the journal Advanced Functional Materials.
The co-lead authors on the research are Yazeed Alaskar, a UCLA graduate student, and Shamsul Arafin, a UCLA post-doctoral scholar in electrical engineering.
Several major material-related challenges were overcome on the way towards realizing such atomically-smooth quasi-epitaxial GaAs (gallium arsenide) thin films on a graphene/silicon system. Most significantly, while the conventional deposition technique requires the growth of one-micron thick GaAs on top of silicon to realize a certain material quality, the UCLA-led group’s innovative and cost-effective growth technique demonstrated that the same quality can be obtained by depositing only 25 nanometers of GaAs atop silicon.
"This is the first time that an ultra-smooth morphology for quasi-epitaxial GaAs thin films on graphene/silicon using an optimized growth technique has been developed,” Shamsul Arafin said. ”It is a remarkable step towards an eventual demonstration of the epitaxial growth of GaAs by this approach for heterogeneous integration." As this technology develops, it could lead to less expensive and high-performance light sources, yielding ultrahigh-speed computers.”
UCLA Engineering would like to acknowledge its collaboration on this research with King Abdulaziz City for Science and Technology (KACST) via the Center of Excellence for Nanotechnologies (CEGN).
