- Quantum photonic integrated circuits require a scalable approach to integrate bright on-demand sources of entangled photon-pairs in complex on-chip quantum photonic circuits. Currently, the most promising sources are based on III/V semiconductor quantum dots. However, complex photonic circuitry is mainly achieved in silicon photonics due to the tremendous technological challenges in circuit fabrication. We take the best of both worlds by developing a new hybrid on-chip nanofabrication approach, allowing to integrate III/V semiconductor nanowire quantum emitters into silicon-based photonics.

Control of spontaneous emission rate in Tamm plasmon structures

Konferensbidrag (refereegranskat)abstract
- We have studied experimentally and theoretically spontaneous emission rate modification in Tamm plasmon structures with semiconductor( InAs/GaAs quantum dots) and organic (CBP) emitters. Time-resolved spectroscopy demonstrates that spontaneous emission rate is increased by one order in magnitude. Experimentally measured spontaneous emission pattern coincides with calculated dependence of modal Purcel factor on frequency and angle of emission.

Modeling the morphology of self-assisted GaP nanowires grown by molecular beam epitaxy
- 2018

- The morphologies of self-assisted GaP nanowires grown by gas source MBE in regular arrays on silicon substrates are modeled by a kinetic equation for the nanowire radius versus the position along the nanowire axis. The most important growth parameter that governs the nanowire morphology is the V/III flux ratio. Sharpened nanowires with a stable radius equal to only 12 nm at a V/III flux ratio of 6 are achieved, demonstrating their suitability for the insertion of quantum dots.

Purcell effect in a disordered photonic crystals
- 2018

Konferensbidrag (refereegranskat)abstract
- We demonstrate that disorder in photonic crystals could lead to a modification of spontaneous emission rate in the frequency region corresponding to a photonic band gap (PBG). Depending on the amount of disorder two different regimes of Purcell effect occurs occurs. For weak disorder Purcell enhancement of spontaneous emission occurs at PBG edges, for strong disorder at PBG centre.
