Article: Demonstration of a nanoparticle-based optical diode.
[show abstract] [hide abstract]
ABSTRACT: We present the operation of an optical device that exhibits diodelike properties based on two adjacent layers of quantum dots (QDs) encased in a fiber-optic jacket. The possibility of a multilayered device is also discussed. A significant change in the emission spectrum of CdSe/ZnS core-shell QDs was observed when excited by the input laser and the fluorescence of other CdSe/ZnS core-shell QDs. The output of the diode can be taken to be either the incoming laser wavelength of light similar to a conventional diode, or the output may be considered to be one of the QD fluorescence wavelengths. Current work has applications in biological fluorescence monitors and sensors as well as in telecommunications applications.Optics Letters 08/2006; 31(13):1957-9. · 3.40 Impact Factor -
Conference Proceeding: Quantum dots based technology for multiple wavelength conversion
[show abstract] [hide abstract]
ABSTRACT: In this paper, we develop basic technology for all optical components used for building (WDM) all-optical switches. We report experimental results related to the emission and response time characteristics of single and a mix of two different types of quantum dots with emission in the visible region. The basic concepts and experiments are much easier to work with when visible light is utilized.Lasers and Electro-Optics Society, 2005. LEOS 2005. The 18th Annual Meeting of the IEEE; 11/2005
