Functional Photonic Circuits Based on Semiconductor Quantum Templates in Quantum Well Structures: Processing-Free Monolithic Integration
Seyed M. Sadeghi,Wei Li +1 more
TL;DR: In this article, the authors propose and numerically demonstrate operation of a processing-free functional photonic integrated circuit based on a semiconductor quantum template, which combines monolayer engineering of the well/barrier interfaces in quantum-well structures with their coherent nonlinear effects to spatially form desired patterns of refractive index, gain and absorption without any need for top-down processes such as lithography, etching, postprocessing epitaxial overgrowth.
Coherently Controlled Time Delay Line and DFB Laser Based on a Single Electromagnetically Induced Photonic Band Gap Structure
Seyed M. Sadeghi,Wei Li,Xun Li,Wei-Ping Huang +3 more
- 24 Apr 2006
TL;DR: In this paper, localized optical modes in electromagnetically induced photonic band gaps are utilized to construct a coherently controlled time delay line or DFB laser, which is controlled by a single infrared laser.
Quantum-biological control of energy transfer in hybrid quantum dot-metallic nanoparticle systems
TL;DR: In this article, it was shown that quantum coherence can introduce a new landscape for the dynamics of Forster resonance energy transfer (FRET), and the effect of variation of R on the FRET rate was investigated.
Impact of photoinduced processes on the plasmonic enhancement of colloidal quantum dot emission
TL;DR: In this article, the mutual effects of photoinduced processes (irradiation effects) and plasmonic emission enhancement in close-packed CdSe/ZnS colloidal quantum dots in the vicinity of gold metallic nanoparticles with two significantly different size distributions were studied.
Inversionless distributed feedback semiconductor lasers: Ultranarrow linewidth and immunity against spatial hole burning
Seyed M. Sadeghi,W. Li +1 more
TL;DR: In this paper, an inversionless intrinsically single-mode distributed feedback laser structure is proposed and parametrically studied, where the laser is optically excited by a control laser field that is responsible for transferring a fully transparent waveguide structure into a coherent state, wherein a periodic variation of gain without inversion in the absence of any refractive index perturbation is generated.
