Surface-emitting laser-its birth and generation of newoptoelectronics field

摘要

The surface-emitting laser (SEL) is considered one of the mostnimportant devices for optical interconnects and LANs, enabling ultranparallel information transmission in lightwave and computer systems. Wenintroduce its history, fabrication technology, and discuss thenadvantages. Then, we review the progress of the surface emitting lasernand the vertical-cavity surface-emitting laser (VCSEL), covering thenspectral band from infrared to ultraviolet by featuring its physics,nmaterials, fabrication technology, and performances, such as threshold,noutput powers, polarizations, line-width, modulation, reliability, andnso on
