Abstract
We take advantage of III-V VeCSEL technology integrating at-photonics for the generation of new coherent states, thanks to insertion of intracavity functions based on at photonics. These new kinds of coherent light states target many applications including optical tweezers, telecommunications, fundamental physics, sensors For this purpose, we extended the VeCSEL semiconductor technology, designing active sections, sub-wavelength metallic masks and photonic crystal, enabling to control the electrical field inside the cavity. This leads to the generation and control of highly coherent single high-order Laguerre- or Hermite-Gauss mode, VORTEX beam carrying controlled orbital-angular-momentum, as well as of coherent dual-frequency wave for THz, and of coherent continuum modeless source.
