Analysis of low-threshold optically pumped III-nitride microdisk lasers
Farsane Tabataba-Vakili, Christelle Brimont, Blandine Alloing +11
Low-threshold lasing under pulsed optical pumping is demonstrated at room temperature for III-nitride microdisks with InGaN/GaN quantum wells on Si in the blue spectral range. Thre…
Monolithic integration of ultraviolet microdisk lasers into photonic circuits in a III-nitride-on-silicon platform
Farsane Tabataba-Vakili, Blandine Alloing, Benjamin Damilano +12
Ultraviolet microdisk lasers are integrated monolithically into photonic circuits using a III-nitride on silicon platform with gallium nitride (GaN) as the main waveguiding layer.…
Correlated electro-optical and structural study of electrically tunable nanowire quantum dot emitters
Maria Spies, Akhil Ajay, Eva Monroy +2
Quantum dots inserted in semiconducting nanowires are a promising platform for the fabrication of single photon devices. However, it is difficult to fully comprehend the electro-op…
Demonstration of critical coupling in an active III-nitride microdisk photonic circuit on silicon
Farsane Tabataba-Vakili, Laetitia Doyennette, Christelle Brimont +11
On-chip microlaser sources in the blue constitute an important building block for complex integrated photonic circuits on silicon. We have developed photonic circuits operating in…
Effect of the nanowire diameter on the linearity of the response of GaN-based heterostructured nanowire photodetectors
Maria Spies, Jakub Polaczyński, Akhil Ajay +5
Nanowire photodetectors are investigated because of their compatibility with flexible electronics, or for the implementation of on-chip optical interconnects. Such devices are char…
III-nitride on silicon electrically injected microrings for nanophotonic circuits
Farsane Tabataba-Vakili, Stéphanie Rennesson, Benjamin Damilano +14
Nanophotonic circuits using group III-nitrides on silicon are still lacking one key component: efficient electrical injection. In this paper we demonstrate an electrical injection…
