Nanophotonic Systems based on Optical Near-Field Interactions on the Nano-Scale

Reference number
Coordinator Kungliga tekniska högskolan - Skolan för informations- och kommunikationsteknik, Verksamhetsbas fotonik och optik
Funding from Vinnova SEK 300 000
Project duration April 2011 - April 2013
Status Completed

Purpose and goal

Research concerning development of low power active nanophotonics systems for ICT sensor etc applications. The research is based on the employment of near field coupled quantum dots, so called Förster coupling, for generating photonic waveguides

Results and expected effects

The research has proven the theoretical feasibility to create the mentioned type of nanophotonics, with properties approaching those of electronics CMOS technology regarding size and power dissipation , but not currently in speed. Further shown was the feasibility to create functions such as modulation and spatial multiplexing in multiwaveguide systems.

Approach and implementation

Theoretical simulations of exciton polaritons propagation along quantum dot waveguides, and the possibility to control this via applied electric fields employing the quantum confined stark effect. Into consideration are taken inhomogeneous broadening, phonon interaction , temperature and dephasing. These simulations, partly presented at major conferences have given the necessary information for experimental realization.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
