We are developing photonic technologies to address climate change. Two papers published in Frontiers in Plant Science and Scientific Reports demonstrate that Raman spectroscopy can be used to guide precision delivery of nitrogen fertilizer thus limiting runoff of excess nitrogen which is a major source of pollution for aquatic ecosystems and of greenhouse gases produced during the manufacture of ammonia. A perspective on how such new sensor technologies can support sustainable farming has been published in Nature Plants.
A technique to incorporate photonic integration in any advanced CMOS technology was reported by Amir Atabaki in Nature. This work follows our earlier demonstration of the first microprocessor with an optical network that was also reported in Nature. This demonstration marks the culmination of a decade of work started at MIT and continued through collaborations at Berkeley and the University of Colorado at Boulder.
A microbioreactor was used to control synthetic gene networks engineered in yeast. The flexibility of this platform was demonstrated through the switchable production of two different therapeutic proteins (interferon and human growth hormone). The experiments were performed by Ningren Han in close collaboration with Pablo Perez-Pinera in Tim Lu’s Group and reported in Nature Communications.
The first integrated photonic platform for trapped ion quantum computing was reported in Nature Nanotechnology. This is the first element of a scalable architecture for integrated trapped ion quantum computing developed by Karan Mehta.
The first microprocessor with an optical network was reported in Nature. This demonstration marks the culmination of a decade of work started at MIT and continued through collaborations at Berkeley and the University of Colorado at Boulder. The work has been widely discussed.
Nature Photonics spotlights Jin Xue’s paper on the first thermophotonic visible LED. This paper demonstrated a blue Gallium Nitride LED whose performance improve as its temperature rises – potentially eliminating the need for heat sinks which are currently the most expensive part of an LED bulb. This demonstration is also seen as a necessary step towards the realization of 100% efficient visible LEDs – building on our previous work demonstrating 100% infrared LEDs.
Ningren Han presents paper on “Microfluidics for Control of Synthetic Biology” at the International Conference on Microsystems for Chemistry and Life Sciences (MicroTAS) in San Antonio, Texas.
Karan Mehta presents a poster on “Nanophotonic and CMOS-integrated Architectures for Trapped Ion Quantum Information Processing” at the International Conference on Atomic Physics in Washington DC.
Karan Mehta’s paper demonstrating a trapped ion qubit on a CMOS chip was published in Applied Physics Letters.
William Loh’s paper demonstrating an optoelectronic filter capable of extracting a weak signal buried 56 dB below a neighboring strong signal 1 GHz away was published in Nature Scientific Reports.
