9. Electrically Injected Tamm Laser Diodes

MAEL LAUPRETRE

24/04/2026 13:35

We present the realization of a new type of laser diode based on surface-confined Tamm plasmon modes, offering an innovative approach for the design of optoelectronic sources that combine high optical performance with technological flexibility. Tamm plasmon modes are electromagnetic modes localized at the interface between a distributed Bragg reflector (DBR) and a metallic layer [1], merging...

27. Theory of transport of bacteria and statistical properties of the run-and-rotate for adherent cells

Feyza BEZIANE (ILM)

24/04/2026 13:50

I'm going to present my work on the theory of the transport of bacteria and the analytical work I've done during my M2 internship on the statistical properties of the run-and-rotate for adherent cells that I'm still studying through simulations.

28. Hexagonal SiGe alloy on Si substrate for Laser

Aamir Ejaz (INL)

Silicon is considered the backbone of the modern telecommunications industry; however, it cannot be used directly as an efficient light source due to its indirect bandgap [1]. Recent studies have shown that Si/SiGe alloys can potentially exhibit direct-bandgap behaviour when their crystal structure is transformed from the conventional cubic phase to the hexagonal phase [2]. This development...

25. "Exploring early galaxy formation with JWST and SPHINX"

Julia Shouse (CRAL)

Since the launch of the James Webb Space Telescope, observations of the high-redshift universe have opened a new window onto the formation of the first galaxies. These early galaxies appear to undergo bursty star formation, which strongly influences their morphology. However, many large-volume cosmological simulations fail to reproduce these features, highlighting the need to better resolve...
