Graphene: changing the world with 2D photonics

In existing technologies, 2D technologies can be introduced
into products such as silicon electronics, semiconductor
nanoparticles, plastics and more for added new
functionality; above; a flexible 2d prototype sensor.
Graphene, anticipated as the next "killer" app to hit optical sensing, is expected to offer an all-in-one solution to the challenges of future optoelectronic technologies, says Frank Koppens. A professor at the Institute of Photonic Sciences (ICFO) in Barcelona, Koppens leads the institute's Quantum Nano-Optoelectronics Group.

Koppens, along with Nathalie Vermeulen of B-PHOT (Brussels Photonics Team, Vrije Universiteit Brussel), will lead a daylong workshop in Brussels on 5 April on transitioning graphene-based photonics technology from research to commercialization.

In his article on Light and Graphene in the current issue of SPIE Professional magazine, Koppens describes the 2D material's tunable optical properties, broadband absorption (from UV to THz), high electrical mobility for ultrafast operation, and novel gate-tunable plasmonic properties.

Two-dimensional materials-based photodetectors are among the most mature and promising solutions, Koppens notes. Potential applications include expanded communications networking and data storage, increased computing speeds, enhanced disease control utilizing increasingly larger and more complex data sets, and more accurate fire, motion, chemical, and other sensor systems including the next generation of wearables.

Graphene is gapless, absorbing light in the ultraviolet, visible, short-wave infrared, near-infrared, mid-infrared, far-infrared, and terahertz spectral regimes. A few of many advantages include:
  • Ability to be monolithically integrated with silicon electronics
  • Extremely fast -- exceeding 250GHz -- as a material-based photodetector
  • Able to bend, stretch, and roll while maintaining useful properties
  • Low-cost production with potential to integrate on thin, transparent, flexible substrates
  • Potential to be competitive against alternate applications in health, safety, security and automotive systems.

Koppens notes that the €1 billion European Union Graphene Flagship program is aiming to work through academia and industry to bring graphene into society within the next 10 years.

#FacesofPhotonics: Rising Researcher Alina Zare

SPIE's #FacesofPhotonics is sharing the story of Alina Zare, Associate Professor at the The Machine Learning and Sensing Lab at the University of Florida. Dr. Zare was recognized as a 2018 Rising Researcher for her work in Electronic Imaging & Signal Processing, at the SPIE Defense + Commercial Sensing conference.

This program recognizes early career professionals who conduct outstanding research in the defense, commercial, and scientific sensing, imaging, optics, or related fields. If you want to learn more about the program, the details are here.

Enjoy the interview with Alina!

1. Tell us about when you first became interested in optics and photonics. In my senior year of  undergraduate studies in computer science, I was taking an Image Processing elective.  I really enjoyed the course, and the professor for the class, Dr. Gerhard Ritter, encouraged me to do some undergraduate research.  
So I joined Dr. Paul Gader's research lab as a undergraduate researcher where I he…

Lighting Their Way

It's a feast for the science-curious senses: in June, two cohorts of two dozen middle-school girls came together for the free, STEM-focused, four-day-long Physics Wonder Girls Camp sessions organized by Dr. Roberto Ramos, associate professor of physics at the University of the Sciences in Philadelphia.

The girls studied the properties of light, built telescopes, designed and engineered submersible robots, and learned about scientific professions directly from the experts: nanoscientist and Chair of Bryn Mawr College's Physics Department Dr. Xuemei Cheng; INTEL software engineer Dr. Marisa Bauza-Roman; and several female food scientists from Puratos, a global company working with bakers and chocolatiers to assess the best ways to improve their products, all came and talked about their professions, answering questions and interacting with the campers. Plus, they got to be on TV!

The camp was initially inspired by Dr. Ramos' daughter Kristiana who expressed interest in the s…

#FacesofPhotonics: University of Arizona Cancer Researcher Kelli Kiekens

SPIE’s #FacesofPhotonics is a showcase across social media that connects SPIE members in the optics and photonics community around the world.

It serves to highlight similarities, celebrate differences, and foster a space for conversation and community to thrive.

This week on #FacesofPhotonics we are sharing the story of Kelli Kiekens, researcher at the University of Arizona in Dr. Barton's lab. From searching for a way to detect cancer earlier, to ballroom dancing, Kelli is a woman of many talents.

We hope you enjoy her interview.

1. Tell us about when you first became interested in optics and photonics. During my undergraduate education, my senior design class concentrated on various topics within optics. The group project for that semester was a study of holography where we created different types of holograms using a few different methods. 


We could then compare the quality of the holograms and see which were better. The part of this project that caught my attention is when we …
