1D and 2D arrays of coupled photonic crystal cavities with a site-controlled quantum wire light source

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Clément William Tendaï Jarlov, Milan Calic

We investigated experimentally 1D and 2D arrays of coupled L3 photonic crystal cavities. The optical modes of the coupled cavity arrays are fed by a site-controlled quantum wire light source. By performing photoluminescence measurements and relying on near ...

High quality factor two dimensional GaN photonic crystal cavity membranes grown on silicon substrate

Nicolas Grandjean, Romuald Houdré, Jean-François Carlin, Raphaël Butté, Jacques Levrat, Antonino Francesco Castiglia, Kirill Atlasov, Georg Rossbach, Noelia Vico Triviño, Ulagalandha Perumal Dharanipathy

We report on the achievement of freestanding GaN photonic crystal L7 nanocavities with embedded InGaN/GaN quantum wells grown by metal organic vapor phase epitaxy on Si (111). GaN was patterned by e-beam lithography, using a SiO2 layer as a hard mask, and ...

Large mode splitting and lasing in optimally coupled photonic-crystal microcavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Kirill Atlasov

Coupling of L-type photonic-crystal (PhC) cavities in a geometry that follows inherent cavity field distribution is exploited for demonstrating large mode splitting of up to similar to 10-20 nm (similar to 15-30 meV) near 1 mu m wavelength. This is much la ...

Phonon-Mediated Coupling of InGaAs/GaAs Quantum-Dot Excitons to Photonic Crystal Cavities

Elyahou Kapon, Alok Rudra, Vincenzo Savona, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Guillaume Jean Tarel, Milan Calic

We demonstrate that the emission characteristics of site-controlled InGaAs/GaAs single quantum dots embedded in photonic crystal slab cavities correspond to single confined excitons coupled to cavity modes, unlike previous reports of similar systems based ...

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 ...

Photonic-crystal microcavity laser with site-controlled quantum-wire active medium

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Milan Calic

Site-controlled quantum-wire photonic-crystal microcavity laser is experimentally demonstrated using optical pumping. The single-mode lasing and threshold are established based on the transient laser response, linewidth narrowing, and the details of the no ...

Effect of sidewall passivation in BCl3/N2 inductively coupled plasma etching of two-dimensional GaAs photonic crystals

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Kirill Atlasov

The effect of surface passivation in BCl3/N-2 inductively coupled plasma reactive-ion etching of GaAs-based photonic crystals (PhCs) was investigated. It is shown that sidewall passivation is crucial for achieving cylindrical, vertical PhC holes, where the ...

Light control and microcavity lasers based on quantum wires integrated in photonic-crystal cavities

Kirill Atlasov

Novel light-emitting devices and micro-optical-circuit elements will rely upon understanding and control of light-matter interaction at the nanoscale. Recent advances in nanofabrication and micro-processing make it possible to develop integrable solid-stat ...
