          | Description: 
             Each square in this image 
            is a vertical cavity surface emitting laser (VCSEL). The center laser 
            is activated by an electrical current supplied by a microscope probe 
            tip, which appears as a dark cone-shaped object. Sandia Labs researchers 
            were able to create a VCSEL that emits the 1.3 micron wavelength light 
            necessary for longer distance fiber-optic transmissions. |
