Quantum computing promises to transform society in all aspects, from the rapid discovery of new drugs and vaccines to improving supply chain efficiency, real-time optimization of transportation and navigation, and the secure storage and transmission of personal information. While there are several contenders for the physical implementation of quantum computers, integrated photonics is advantageous for several reasons.

Photonic isolators are essentially diodes for optical signals, and as such they prevent backward propagation of light as needed, most frequently in front of lasers as protection from reflected power. After introducing the phenomenon of non-reciprocity, the operation of commercial (bulk) isolators will be discussed, including magneto-optical Faraday rotation which is prevalent in iron garnets.  Although commercial isolators have their own markets, future hyperscale data needs are moving ever closer to integrated photonics as pluggable transceivers are replaced by co-packaged optics.

In this talk I will review advances in optical frequency comb implementations of so-called electro-optical (EO) frequency combs, based on phase and intensity modulation of a stable carrier. Stable frequency comb operation spanning over an octave and subsequent self-referencing was recently achieved by the NIST group (Beha et al., 2017). This inspires different implementations of EO frequency combs, including fiber based systems and photonic integrated circuit approaches.

The development of computing systems able to address our ever-increasing needs, especially as we reach the end of CMOS transistor scaling, requires truly novel methods of computing. My research draws inspiration from biology, rethinks the digital/analog boundary, and challenges conventional wisdom, which typically guides how we perform computation, by reimagining the role of time. In this talk, I first introduce a computational temporal logic that sets the foundation for temporal computing.

There is great promise and potential in artificial intelligence (AI), but if such technologies are built and trained by humans, are they capable of bias?

Absolutely, says William Wang, the Duncan and Suzanne Mellichamp Chair in Artificial Intelligence and Designs at UC Santa Barbara, who will give the virtual talk “What is Responsible AI,” at 4 p.m. Tuesday, Jan. 25, as part of the UCSB Library’s Pacific Views speaker series .

The Institute for Energy Efficiency at the University of California, Santa Barbara invites you to attend the annual 2019 Emerging Technologies Review on Thursday, May 16th. This all-day review (8:30-5pm) will feature several speakers, covering new developments in areas of energy and energy efficiency.

Divided into several distinct sessions, industrial and academic speakers will cover a broad range of topics in areas such as Production & Storage, Computing & Datacenter Energy Efficiency, Food-Water-Energy Nexus, and Societal Energy Infrastructure. 

In this special year, The Institute for Energy Efficiency at UC Santa Barbara held three virtual workshops as part of the 2020 Emerging Technologies Review.

The ETR virtual workshops covered new developments in: Energy Efficient Clouds and Data Centers on October 2nd; Smart Societal Infrastructure on October 16th; and Food-Energy-Water on October 23rd. Each virtual workshop featured world class experts and leaders in that arena from industry, academia and government.
 

The Institute for Energy Efficiency at UC Santa Barbara invites you to attend our 2022 Emerging Technologies Review. This year, IEE ETR will be a 2-day virtual workshop on January 20th & 21st. 

The ETR virtual workshops will cover new developments in: Energy Efficiency in Buildings in the Post-COVID-19 Era on January 20th, and Future Data Center Architectures and Increased Energy Efficiency on January 21st. Each virtual workshop will feature world class experts and leaders in that arena from industry, academia, and government.

On many days, California now generates more than half of our electricity from renewable energy sources, especially solar and wind farms. Renewables are intrinsically weather-driven, introducing major new uncertainties into the daily balancing of grid load and power generation. Large deviations between forecasted and realized renewable production are frequent and impose significant additional cost on running the grid.
