Three Simple Steps to Networking Sucess at AIO 2014

By Arlene Smith, Ph.D. | Posted: 16 June 2014

Behind-the-scenes preparations for AIO 2014 are well underway.  As I obsessively check the Seattle weather forecast and celebrate the end of sessioning (a committee member benefit!), I’m reminded what makes this meeting unique. In this blogpost, I want to raise a topic that is near-essential for career progression, but can strike fear into the hearts of the introverted. I want to talk about networking. I fear rejection just like you.

If the thought of speaking with your optics idol or asking a question makes you queasy, I hope the following approach opens up a world of conversations for you. Try it out at AIO.

CLEO:2014 -- The fractal conference

By Arti Agrawal | Posted: 11 June 2014

The CLEO conference is this week and this time I presented a short course: SC410, Finite Element Modelling Methods for Photonics and Optics. However, as always, there is more than a presentation to make. There are several talks I am looking forward to hearing (not including the ones I haven’t yet marked out in the conference planner):

David Payne’s plenary on “Fibers and the future”; Thomas Moore’s invited talk on Artificial Photosynthesis, M . Segev’s invited talk on Photonic Topological Insulators and the 2 entire sessions on Photovolatic Sciences and Novel Anisotropic Structures. There are talks on photonic hyper crystals!!

Nanophotonics at CLEO:2014

By Howard Lee | Posted: 10 June 2014

Some sessions of interest to nanophotonics at CLEO:2014.

Sensing for chiral molecule using metasurface
Dr. Yang Zhao (FM3K.6) have an interesting talk. As there is serious demand to determine the chirality of molecules for achieving enantiomer-pure chiral drugs, many researches have been carried out to use optical chirality for sensing chiral molecules. However, when the amount of molecules is small, using optical chirality for sensing is normally not efficient. Zhao discussed in her talk how they use a near field chiral enhancement in a metallic metasurface to detect those molecules through circular dichroism (CD). The multilayer metasurface is made of gold by multiple e-beam lithography steps. The second layer of patterns is twisted with certain angle with respect to the first layer (see figure below), which leads to the origin of the CD. Using an analytical approach together with the design and fabrication of the metastructure, they demonstrated CD signal measurements for monolayer of protein. They also showed the metasurface provides an ultra-sensitive probe to enhance CD measurements which can not be achieved in typical optical materials and structures.
