In this talk we'll present the latest results on the integration of silicon-photonic interconnects into a monolithic platform (45nm SOI logic process and bulk CMOS memory periphery process). These include world's first microprocessor communicating to the outside world with monolithically integrated Si-Photonic devices, as well as the first demonstration of photonics in a bulk CMOS process.

The production and use of engineered nanoparticles (ENP) inevitably leads to their release into aquatic environments. Concerns therefore arise over the possibility that ENPs might pose a threat to consumers and the environment. Investigations on the vulnerability of natural systems to ENPs are hampered by the absence of suitable analytical methods that are capable of detecting and quantifying ENPs in complex aqueous matrices. Analytical data concerning the presence of ENPs is therefore scarce.

I will discuss two main themes of research in my group addressing nano-photonics on silicon.  I will discuss recent advances on nanopillar devices based on III-V compound directly grown on silicon.

The UCSB Office of Technology & Industry Alliances is pleased to present a panel discussion of how to prepare for a successful and smooth launch of a new startup company - from assuring legal issues are in order to attracting and maintaining early investment.

Join the UCSB Photonics Society for their 2017 Light Science Workshop for a day of talks and presentations about the cutting edge in photonics research and career opportunities in this blossoming industry. The event will feature a keynote speaker, technical and non-technical presentations, Q&A panels, a job fair and a poster session!

The use of petroleum in transportation causes air pollution, water pollution, climate change, instability in energy markets, and other problems. In this talk, I draw on a wide range of energy, economic, environmental, and socio-demographic analyses to show that the best way to address these problems is to electrify transportation as part of an energy system based (almost) entirely on wind, water, and solar power.

You are invited to a Workshop on Science, Communication, and Uncertainty, Thursday, May 4, 2:00 – 4:45pm, in the UCen State Street Room. See http://sustech.ucsb.edu/conferences/2017-science-communication-and-uncertainty-workshop.
 

There is often a natural assumption that “perfect form” of a material is required to produce “perfect functioning” of a device, where the function may relate to precision sensing, or the storing or transmission of information. Recently, however, there has been excitement about the performance of defects in crystalline semiconductors such as diamond and SiC. The defects are deviations from perfect, periodic crystalline order, yet can manifest optical emission at a variety of wavelengths, distinctively coupled to long spin coherence times.

Silicon photonics offer a tight integration of a variety of active and passive optical and electrical components, and gained so much interest in the last decade that it is now considered one of the most promising technology for photonics applications [1]. Building on the mature fabrication techniques first developed for microelectronics allows creating photonic integrated circuits (PICs) with a high density of optical components, in high volumes and at low costs.
