Structured light from Photonic & THz coherent sources based on III-V semiconductor laser technology

Résumé

3D Structured coherent electromagnetic field emitting in the optical and/or THz spectral domain is a hot topic and of great interest for a large panel of applications in opto-hyper field, both in the fondamental and applied domains: telecom, LIDAR, sensing, optical tweezers, biophotonics, spectroscopy... We will present an overview of our recent results on 3D (time-space) structured coherent electromagnetic field [1,2,4], emitting in the near-IR and THz spectral domain. These photnic devices are based on III-V semiconductor VECSEL laser technology [3], and exploiting parity symmetry-breaking together with metasurafce and photo-conductive antenna nanotechnology. We demonstrated a vortex laser with controlled orbital angular momentum allowing both linearrotationnal doppler based speed sensing under light matter-interaction [1], spatially modeless laser and light multiplexing [4], non-linear structured light [4,5], dual-mode laser based tunable coherent THz emitter [2]... We will discuss the ongoing work towards light bullets photonic device, multiplex structured coherent photonic sources and plasmonics photomixer based powerfull cw THz emitter, of great interest for challenging applications.
