A novel method for making a high efficiency and lower power Vertical Cavity Surface Emitting Laser.
A Vertical Cavity Surface Emitting Laser (VCSEL) is a semiconductor laser including a semiconductor layer of optically active material sandwiched between mirror stacks formed of highly-reflective layers of material.
Researchers at the University of California, Santa Barbara have developed a novel method for making a high efficiency and lower power Vertical Cavity Surface Emitting Laser. This method includes the introduction of a new VCSEL structure and fabrication technique that will decrease power loss across the laser for high efficiency output with low optical loss. This method is fully comprehensive and can be carried through using existing fabrication techniques.
