Title:
PHOTON PAIR SOURCE AND METHOD FOR ITS PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2010/012268
Kind Code:
A3
Abstract:
The invention relates to a method for the production of a photon pair source, which generates entangled photon pairs, having at least one quantum dot, wherein in the method the operational behaviour of the photon pair source is determined by adjusting the fine structure splitting of the excitonic energy level of the at least one quantum dot. It is provided according to the invention for the fine structure splitting of the excitonic energy level to be adjusted by depositing the at least one quantum dot on a {111} crystal surface of a semiconductor substrate.
