Semiconductor quantum light sources

Applying quantum light states to photonic applications allows functionalities that are not possible using ‘ordinary’ classical light. For example, carrying information with single photons provides a means to test the secrecy of optical communications, which could soon be applied to the problem of sharing digital cryptographic keys1,2. Although secure quantum-key-distribution systems based on we...

A new semiclassical model to analyze sub-Poissonian light in high-impedance-driven semiconductor light emitters

We propose a new and simple semiclassical model to analyze sub-Poissonian light in high-impedance, constant-current-driven semiconductor light emitters, and obtain some new and interesting results. Our study shows that the model gives a simple and distinct physical picture to explain the suppression mechanism of intensity noise in high-impedance-driven semiconductor light emitters.  2001 Elsev...

Slow light in semiconductor heterostructures

This paper presents an overview of slow light in semiconductor heterostructures. The focus of this paper is to provide a unified framework to summarize and compare various physical mechanisms of slow light proposed and demonstrated in the past few years. We expand and generalize the discussions on fundamental limitation of slow light and the delay–bandwidth product trade-off to include gain sys...

High visible-light photochemical activity of titania decorated on single-wall carbon nanotube aerogels

Photocatalysts are being extensively investigated to convert renewable solar energy into chemical energy but suffer from high costs or low efficiencies. We report on the development of highly visible-light photoactive composites of titania (TiO2) and single-wall carbon nanotubes (SWCNTs) that rapidly photodegrade methylene blue dyes under visible-light illumination in the absence of cocatalysts...
