ORC Seminar Series

“Photonic organic nanomaterials”

Speaker: Professor Igor Yu. Denisyuk

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


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.


Igor Yu. Denisyuk, Professor, Doctor of science, PhD, is Head of the Department of "Optic of Quantum Sized Systems” and Director of the centre  “Polymeric integrated optics and nanomaterials” at the University of Information Technologies, Mechanics and Optics, Saint-Petersburg State, Russia. He has over 60 published works.
