Description
With
today’s technology, radio frequency front-end architectures are very similar
in radar and wireless communication systems. Further, in an effort to access
more bandwidth, wireless systems have been shifting to frequency bands that
have been traditionally occupied by radar systems. Given the hardware and
frequency convergence, there is a lot of recent interest in the integration
of the radar and communication functions in one system. Such integration will
enable more efficient use of spectrum, reduce device size/cost and power
consumption, and will also offer the potential for significant performance
enhancement of both sensing and communication functions. Dual Function
Radar-Communication (DFRC) systems is a class of integrated
sensing-communication (ISC) systems that use the same waveform as well as the
same hardware platform for both sensing and communication purposes. Thus, DFRC
systems can achieve higher spectral efficiency than most ISC systems, require
simpler transmitter hardware and a smaller, less expensive device. DFRC
systems are prime candidates for autonomous driving vehicles, unmanned aerial
vehicles, surveillance, search and rescue, and networked robots in advanced
manufacturing applications that rely on censing and communications.
In
the talk, we will present a novel DFRC system that uses the available
bandwidth efficiently for both communication as well as sensing. The system
transmits wideband, orthogonal frequency division multiplexing (OFDM)
waveforms and allows the transmit antennas to use subcarriers in a shared
fashion. When all subcarriers are used in a shared fashion, the proposed
system achieves high communication rate, while its sensing performance is
limited by the size of the receive array. By reserving some subcarriers for
exclusive use by transmit antennas (private subcarriers), the communication
rate can be traded off for improved sensing performance. The improvement is
achieved by using the private subcarriers.

Description
Humans
have recorded the appearance of “new stars” since prehistory, but only in the
last century have astronomers begun to understand their nature as stellar
explosions. These “supernovae” provide clues about the lives and deaths of
stars, the formation and evolution of galaxies, the production and distribution
of chemical elements (including those required for life on Earth), and even
the accelerating expansion of the Universe.
In
the last two decades, the discovery rate of supernovae has ballooned from
hundreds per year to tens of thousands per year, and in the coming decade, it
will reach into the millions. This explosion can be traced back to the same
technological advances behind the Internet age: high-speed
telecommunications, digital imaging, increased computer processing power, and
machine learning. This presentation will explore the history and future of
supernova observations, with a focus on the technology behind them and the
science they enable.

Speaker
Dr.
Griffin Hosseinzadeh is a postdoctoral researcher at Steward Observatory at
the University of Arizona, where he studies various types of stellar
explosions. He was previously a postdoctoral researcher at the Center for
Astrophysics | Harvard & Smithsonian. He received his bachelor’s in
physics from UC Berkeley in 2012 and his Ph.D. in astrophysics from UC Santa
Barbara in 2018.

Co-Packaged Silicon-Photonics Based Optical Transceivers for High-Speed
Datacenter Interconnects

Description
Silicon
photonics based optical interconnects (I/O) are being explored as a viable
alternative to circumvent the reach, bandwidth and power limitations of
electrical interconnects for data-centers. Current high-volume products for
optical data-center interconnects are in the form of pluggable modules
composed of discrete electronics and photonics ICs that plug into server
racks. These modules are still limited in energy efficiency due to the
relatively long (inches-long) high-speed electrical interconnect between the
pluggable module and the processing unit (XPU). However, recent advances in
ultra-compact silicon-based optical modulators and integrated lasers, along
with a migration of the interface electronics to densely-integrated silicon
processes have led to the development of compact optical I/O modules. These
can be collocated on the same package as the XPU (‘co-packaged’) to reduce
the length of the high-speed electrical interconnect between the XPU and the
optical module to only a few centimeters resulting in advantages in energy
efficiency and shoreline bandwidth density. In this talk, I will review
prototypes of our silicon-based intensity-modulated optical transceivers and
our recent work on scaling optical I/O data-rates at iso-energy efficiency
through the use of dense wavelength division multiplexing (DWDM).
