| Title: |
Quantum Dot Lasers: One Dot Makes All the Difference |
| Description: |
Microdisk lasers used in experiments by NIST, Stanford University and Northwestern University are made by layering indium arsenide on top of gallium arsenide and etching out disks about 1.8 micrometers across on pillars of gallium arsenide. Scanning tunneling microscope image (inset) shows some of the approximately 130 "quantum dot" islands of indium arsenide in each disk.
