Reduced lasing thresholds in GeSn microdisk cavities with defect management of the optically active region
Anas Elbaz, Riazul Arefin, Emilie Sakat +20
GeSn alloys are nowadays considered as the most promising materials to build Group IV laser sources on silicon (Si) in a full complementary metal oxide semiconductor-compatible app…
Möbius Strip Microlasers: a Testbed for Non-Euclidean Photonics
Yalei Song, Yann Monceaux, Stefan Bittner +9
We report on experiments with Möbius strip microlasers which were fabricated with high optical quality by direct laser writing. A Möbius strip, i.e., a band with a half twist, exhi…
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.…
Ultra-low threshold cw and pulsed lasing in tensile strained GeSn alloys
A. Elbaz, D. Buca, N. Von den Driesch +15
GeSn alloys are the most promising semiconductors for light emitters entirely based on group IV elements. Alloys containing more than 8 at.% Sn have fundamental direct band-gaps, s…
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…
Blue Microlasers Integrated on a Photonic Platform on Silicon
Farsane Tabataba-Vakili, Laetitia Doyennette, Christelle Brimont +12
The main interest of group-III-nitride nanophotonic circuits is the integration of active structures and laser sources. A photonic platform of group-III-nitride microdisk lasers in…
Q factor limitation at short wavelength (around 300 nm) in III-nitride-on-silicon photonic crystal cavities
Farsane Tabataba-Vakili, Iannis Roland, Thi-Mo Tran +10
III-nitride-on-silicon L3 photonic crystal cavities with resonances down to 315 nm and quality factors (Q) up to 1085 at 337 nm have been demonstrated. The reduction of the quality…
High-performance and power-efficient 22 optical switch on Silicon-on-Insulator
Zheng Han, Gregory Moille, Xavier Checoury +4
A compact (15μmμm) and highly-optimized 22 optical switch is demonstrated on a CMOS-compatible photonic crystal technology. On-chip insertion loss are below 1dB…
Unidirectional band gaps in uniformly magnetized two-dimensional magnetophotonic crystals
Mathias Vanwolleghem, Xavier Checoury, Wojciech Śmigaj +6
By exploiting the concepts of magnetic group theory we show how unidirectional behavior can be obtained in two-dimensional magneto-photonic crystals (MOPhC) with uniform magnetizat…
