ORC Seminar Series

“Photonic organic nanomaterials”


Speaker: Professor Igor Yu. Denisyuk

Date: Friday 27 July 2007
Venue: Lecture Theatre B (Building 46)
Time: 2pm

Abstract

This talk will present results from investigations made by a group of scientists during 2001 – 2007 in the fields of

  1. high refractive index polymeric optical nanocomposites materials based on ZnS nanoparticles with high concentrations in polymeric matrix
  2. non-linear and electro-optic materials based on DAST nanocrystals in polymeric matrix and flat thin crystalline films
  3. self – written in photopolymerizable composition microlenses on top of the fibre and waveguides

Topic (1) is connected to the problem of stabilisation of nanoparticles with a high concentration of up to 25% volume in polymeric films and its optical properties. This work was accomplished under the support of a CRDF grant in collaboration with 3M Corp. US.

Topic (2) is an investigation of organic nonlinear optical materials with high electro-optic coefficient (400 – 500 pm/V) for low-voltage light modulators.

Topic (3) is connected to the effect of self-focusing of light in UV-curable composition and its application for formation of microstructures in the top of the fibre.
