Latest Patents

Julien Boucart holds a patent for a surface emitting semiconductor laser. This invention features two semiconductor layers that form a tunnel junction, allowing an electrical current to pump the laser. The current passes from an N-doped semiconductor Bragg mirror to a P-doped injection layer within the light-amplifying structure. The Bragg mirror works in conjunction with another mirror of the same type, which has similar doping, to create an optical cavity for the laser. In a variant of the design, the tunnel junction may be buried and positioned to serve as confinement means for the pumping current. This laser technology is particularly useful in optical fiber communications networks.
