Altering Compact Semiconductor Lasers For More Practical Holograms

Researchers have developed a way to modify the coherence of vertical-cavity surface-emitting lasers using chaotic cavities. Semiconductor technology enables all components of a laser to be compactly packaged into a device that is only a few micrometers in size. This includes an optically active region that amplifies light and highly reflective mirrors on both sides. […]
