NEWAVE project : waveguide polariton lasers
NEWAVE (ANR project, 2022-2025)
New concepts for waveguide micro- and nano-lasers
- Project coordinator : Thierry Guillet (CV), Laboratoire Charles Coulomb, Montpellier
- Project goal : exploring new operation modes for micro- and nano-lasers for integrated photonics, based on polaritonic quantum fluids of light.
- Partners :
- L2C, Montpellier
- CRHEA, Sophia Antipolis
- C2N, Saclay
- Institut Pascal, Clermont-Ferrand
- ANR Collaborative Research Program (PRC),
- Contract ANR-21-CE24-0019-01
- within CE24 (Micro et nanotechnologies pour le traitement de l’information et la communication)
The foreseen microlasers are based on polaritonic waveguides (GaN), an "all-in-one" active medium that is very different from usual semiconducting active layers, thus revisiting in depth the laser mechanisms.
They provide a very strong gain, low absorption losses and a self-focusing non-linearity.
The challenge is to control the laser dynamics by patterning photonic crystal waveveguides in order to realise continuous-wave or pulsed laser sources (with an ultra-low energy per pulse), and then a topological laser including an intra-cavity optical isolator.
This project should open new mid-term perspectives for important applications in integrated photonics, topological photonics and photonic quantum simulators.
