Selective Effects of the Host Matrix in Hydrogenated InGaAsN Alloys: Toward an Integrated Matrix/Defect Engineering Paradigm

In dilute nitride InyGa1-yAs1-xNx alloys, a spatially controlled tuning of the energy gap can be realized by combining the introduction of N atoms-inducing a significant reduction of this parameter-with that of hydrogen atoms, which neutralize the effect o ...

Polarization properties and disorder effects in H-3 photonic crystal cavities incorporating site-controlled, high-symmetry quantum dot arrays

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Alessandro Surrente, Pascal Gallo, Marco Felici

We report on the effects of optical disorder on breaking the symmetry of the cavity modes of H-3 photonic crystal cavities incorporating site-controlled pyramidal quantum dots (QDs) as the internal light source. The high in-plane symmetry of the polarizati ...

Magneto-optical properties of single site-controlled InGaAsN quantum wires grown on prepatterned GaAs substrates

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Romain Carron, Pascal Gallo, Marco Felici

The properties of single site-controlled InGaAsN quantum wires (QWRs)-both untreated and irradiated with atomic hydrogen-are probed by micro-magnetophotoluminescence spectroscopy. The strong anisotropy of the diamagnetic shift measured for different orient ...

Reduced temperature sensitivity of the polarization properties of hydrogenated InGaAsN V-groove quantum wires

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Romain Carron, Marco Felici

We investigated the effects of hydrogen irradiation on the degree of linear polarization, rho, of the light emitted by site-controlled, dilute-nitride InGaAsN V-groove quantum wires (QWRs). While in the as-grown sample the polarization of the QWR emission ...

Ordered systems of site-controlled pyramidal quantum dots incorporated in photonic crystal cavities

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Alessandro Surrente, Pascal Gallo, Marco Felici

The coupling of a prescribed number of site-controlled pyramidal quantum dots (QDs) with photonic crystal (PhC) cavities was studied by polarization and power-dependent photoluminescence measurements. The energy of the cavity mode could be readily tuned, m ...

Semianalytical approach to the design of photonic crystal cavities

Elyahou Kapon, Kirill Atlasov, Alessandro Surrente, Marco Felici

Most current methods for the engineering of photonic crystal (PhC) cavities rely on cumbersome, computationally demanding trial-and-error procedures. In the present work, we take a different approach to the problem of cavity design, by seeking to establish ...

Dense arrays of pyramidal quantum dots with narrow linewidth photoluminescence spectra

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Alessandro Surrente, Pascal Gallo, Marco Felici

Arrays of site-controlled, pyramidal InGaAs/GaAs quantum dots (QDs) grown by organo-metallic chemical vapour deposition with densities comparable to those of self-assembled QDs (5 x 109 cm(-2)) are demonstrated. The QDs exhibit high quality photoluminescen ...
