Welcome to the alpha version of Lightnotes.info! We are not sure how you came across our blog, but we are glad to see you here.

The website and blog are both still under construction, which we decided to do live. Stick around to watch our work in progress, or come back few weeks later for our reviews of the most interesting things in the world of nanophotonics.

Arseny (Arseniy) Alexeev

I am an accomplished R&D leader with broad practical experience and strong background in theory of condensed matter physics. I develop novel optical and electronic devices, including diffractive and metamaterial based optical components, chemical sensors based on 2D materials and plasmonic nanostructures, non-volatile resistive switching and optical memories, flexible electronic components, and in the past 3 years, augmented reality displays.

I have more than 15 years of combined academic and industrial R&D experience, more than 25 journal publications, several patent applications. I am well connected within different research communities (2D materials, nano-photonics, metamaterials) and industrial fields (display technologies, augmented reality, resistive switching memories, nanofabrication and metrology).
