Deterministic positioning single site-controlled high symmetric InGaAs quantum dots (QDs) in (111)B-oriented GaAs photonic crystal cavities with nanometer-scale accuracy provides an idea component for building integrated quantum photonic circuits. Ho

We demonstrate high-resolution cryogenic photoluminescence measurements on exciton complexes emitting ≈ 1 µm of a single-site-controlled highly-symmetric quantum dot-nanocavity system. Observed fine spectral features uncover the C3 v QD symmetry a

Precise positioning of single quantum dots (QDs) in photonics crystal (PhC) cavities with nanometer-scale accuracy offers great promise for on-chip integrated quantum photonic circuit. In such coupled QD-cavity system, the decoherence fundamentally a

We demonstrate the controllable exciton-cavity mode interaction mediated by pure dephasing in a single site-controlled quantum dot-nanocavity system. With varying detuning, Purcell enhanced dynamics and phonon-assisted cavity feeding sequentially dom

A system of two site-controlled semiconductor quantum dots (QDs) is deterministically integrated with a photonic crystal membrane nano-cavity. The two QDs are identified via their reproducible emission spectral features, and their coupling to the fun

Growth of InGaAs/GaAs quantum dots (QDs) in inverted pyramids on pre-patterned {111}B GaAs substrates is a versatile technique allowing for precise site and emission energy control. We report on the fabrication of QDs with a wavelength setting within

Partial suppression of the spectral diffusion of quantum dot (QD) excitons tuned to resonance of a nano-photonic cavity is reported. The suppression is caused by the Purcell enhancement of the QD-exciton recombination rate, which alters the rate of c

Rectangular arrays of pyramidal recesses coated by silver film are investigated by means of polarization-resolved nonlinear microscopy at 900 nm fundamental wavelength, demonstrating strong dependence of the dipole-allowed SHG upon the lattice parame

We investigate a photonic crystal structure where distant, identical nanocavities incorporating site-controlled semiconductor quantum dots are coupled with a bus waveguide. We show that the cavities can be resonant frequency matched even upon fabrica

We describe the fabrication, epitaxial growth and photoluminescence (PL) spectra of systems of site-controlled pyramidal quantum dots (QDs) integrated with photonic crystal (PhC) membrane cavities. The spectra of the individual QDs are characterized
