Enhanced Photoluminescence from Embedded PbSe Colloidal Quantum Dots in Silicon-Based Random Photonic Crystal Microcavities
نویسندگان
چکیده
The experimental observation of enhanced photoluminescence from high-Q silicon-based random photonic crystal microcavities embedded with PbSe colloidal quantum dots is being reported. The emission is optically excited at room temperature by a continuous-wave Ti-sapphire laser and exhibits randomly distributed localized modes with a minimum spectral linewidth of 4 nm at 1.5 μm wavelength.

Near-field mapping of quantum dot emission from single-photonic crystal cavity modes
We directly investigate, by means of near-field spectroscopy, the spatial distribution of the optical cavity modes of 2D photonic crystal microcavities. Numerical simulations confirm that the photoluminescence maps of quantum dots embedded in the photonic structure qualitatively match the spatial modulation of the electric field intensity. r 2007 Elsevier B.V.

متن کاملLocal nanofluidic light sources in silicon photonic crystal microcavities.
We report on the realization of a rewritable and local source inside a Si-based photonic crystal microcavity by infiltrating a solution of colloidal PbS quantum dots inside a single pore of the structure. We show that the resulting spontaneous emission from the source is both spatially and spectrally redistributed due to the mode structure of the photonic crystal cavity. The coupling of the qua...
متن کاملEnhanced Telecom Emission from Single Group-IV Quantum Dots by Precise CMOS-Compatible Positioning in Photonic Crystal Cavities
Efficient coupling to integrated high-quality-factor cavities is crucial for the employment of germanium quantum dot (QD) emitters in future monolithic silicon-based optoelectronic platforms. We report on strongly enhanced emission from single Ge QDs into L3 photonic crystal resonator (PCR) modes based on precise positioning of these dots at the maximum of the respective mode field energy densi...
متن کاملCavity Enhancement of Single Quantum Dot Emission in the Blue
Cavity-enhanced single-photon emission in the blue spectral region was measured from single InGaN/GaN quantum dots. The low-Q microcavities used were characterized using micro-reflectance spectroscopy where the source was the enhanced blue output from a photonic crystal fibre. Micro-photoluminescence was observed from several cavities and found to be ~10 times stronger than typical InGaN quantu...
متن کاملDeveloping PbSe/PbS Core-Shell Nanocrystals Quantum Dots (NQDs) for NQD/Silicon Heterojunctions
We report in this paper the epitaxial growth of PbS shells over PbSe nanocrystal quantum dots (NQDs) with monolayer-precision. The core-shell infrared NQDs were ligand-exchanged with short-chain octadmine, and the photoluminescence efficiency of the surface-engineered core-shell nanoparticles was substantially higher than that of the plain core structures undergoing the same surface processing,...
