innovation for industry
Optically pumped germanium-tin micro-disks encapsulated by silicon nitride and transferred onto aluminum pillars generate a 2.5-micron laser beam with an ultra-low threshold. Laser beams with no III-V materials are no longer a dream… See results published in Nature Photonics.
Our ultimate goal is to produce IV-IV lasers that operate in the mid-infrared range, explains Jean-Michel Hartman, CEA-Leti researcher.
