Rajeev Ram is Professor of Electrical Engineering at MIT. His research focuses on the development of novel photonics & electronics for communications, energy, and sensing.
- Demonstrated trapped ion qubits with long-lifetime and long-coherence in a CMOS integrated circuit.
- Demonstrated first photonic communication link in bulk CMOS in collaboration with UC Berkeley.
- Demonstrated low power optical communication using a thermoelectrically pumped LED.
Key Research Milestones:
- On the team that demonstrated <5 fJ/bit resonant Silicon photonic modulator and <20 fJ/bit integrated transmitter (2013).
- Demonstration of a thermally pumped light-emitting diode – first light-source to achieve greater than 100% electrical-to-optical conversion efficiency (2012)
- CMOS photonics in a deep-submicron technology (2008).
- Demonstration of a lab-on-a-chip microbioreactor for scale-down bioprocessing (2006)
- Measurement of thermoelectric parameters inside p-n junction (2004)
- Room temperature, continuous-wave lasers on Si using graded SiGe/Si interlayers (2002)
- Proposed telecom switch based on electromagnetically induced transparency (2000)
- First room temperature, continuous-wave bipolar cascade laser (1999)
- Proposed semiconductor polariton laser (1996)
- Proposed semiconductor laser without population inversion (1994)
- On the team that produced the first electrically pumped, telecom VCSEL (1993)
- Developed III-V wafer bonding process (eg. high brightness LEDs) (1992)
More than two dozen graduate and post-doctoral researchers have worked with Ram in the Physical Optics and Electronics Laboratory. These students have gone onto leading semiconductor companies such as Intel, Sun, Samsung and Freescale as well as to tenured faculty positions at Cornell, the University of California, the University of Michigan, and MIT.
He has received the Ruth and Joel Spira Award and Jamieson Award for teaching. He is a MacVicar Faculty Fellow – MIT’s highest honor for teaching.
Until June 2012, he served as a Program Director at the Advanced Research Projects Agency within the Department of Energy. He joined ARPAe in its first year. His primary focus was in advanced electrical components and systems ranging from transportation to the generation and transmission of electric power. He created three programs at ARPAe: Agile Delivery of Electrical Power Technology (ADEPT), Solar ADEPT (part of the President’s Sunshot Initiative), and Green Electricity Network Integration (GENI). His portfolio of projects exceeded $100M and included the demonstration of the highest voltage transistor ever-made and supported the breakthrough development of GaN-on-Si power electronics technology. He worked closely with start-ups (Transphorm, Varentec, Foro Energy, FastCap, APEI), supported cutting-edge research at companies including IR, Cree, GE, GM, Toyota, and consulted with the Office of Science and Technology Policy and the White House
