U.S./Middle East Conference on Photonics
November 4 @ 9:00 am - November 6 @ 5:30 pm This conference seeks to strengthen engagement between U.S., European, and Middle Eastern scientists by providing a forum for discussion of cutting edge photonics research. “It is indeed inspiring to use the power of science and scientific curiosity to bring people together irrespective of their background, gender or race.” – Hatice Altug, École Polytechnique Fédérale de Lausanne (EPFL)
Researchers Develop a Structure Capable of Long-Term Storage and Controlled Release of Mechanical Waves Without Energy Loss
NEW YORK, August 30, 2019 — Light and sound waves are at the basis of energy and signal transport and fundamental to some of our most basic technologies — from cell phones to engines. Scientists, however, have yet to devise a method that allows them to store a wave intact for an indefinite period of time and then direct it toward a desired location on demand. Such a development would greatly facilitate the ability to manipulate waves for a variety of desired uses, including energy harvesting, quantum computing, structural-integrity monitoring, information storage, and more.
Photonics Seminar: Barry P. Rand, Princeton University
Date: October 21 Time: 11:00 am - 12:00 pm Event Category: Photonics ASRC Auditorium 85 St. Nicholas Terrace New York,NY10031 United States Title: Devices emerging from controlling organic and metal halide perovskite energetics and morphology Abstract: In this seminar, we will focus on our recent work on two different thin film systems – metal halide perovskites and organic semiconductors. For organic semiconductors, through proper control of processing, we are able to realize pinhole free films with grains of up to 500 μm in extent. we have found that charge transfer (CT) states incorporating these long-range-ordered films can be highly delocalized, contributing to noticeably lower energy losses. Also, we have [...]

Photonics Seminar: Kevin Cognee, AMOLF
Date: August 8 Time: 2:00 pm – 3:00 pm Event Category: Photonics ASRC Auditorium 85 St. Nicholas Terrace New York, NY 10031 United States Hybrid metallo-dielectric nanophotonic platforms: how can we benefit from coupling plasmonic antennas and dielectric cavities? Abstract – It has been recently proposed that nanophotonic platforms composed of metallic nano-antennas and dielectric microcavity could enhance light matter interaction further than what is allowed by its individual components by combining both strong field confinement and high quality factors. We further explore this concept of “hybrid metallo-dielectric resonators” which also allows for an additional control over radiation properties, in particular in the context of microdisk cavities supporting whispering gallery modes dressed by phased [...]
