Abstract
A vertical-cavity surface emitting laser (VCSEL) was invented 30 years
ago. A lot of unique features can be expected, such as low-power
consumption, wafer-level testing, small packaging capability, and
so on. The market of VCSELs has been growing up rapidly in recent
years, and they are now key devices in local area networks using
multimode optical fibers. Also, long wavelength VCSELs are currently
attracting much interest for use in single-mode fiber metropolitan
area and wide area network applications. In addition, a VCSEL-based
disruptive technology enables various consumer applications such
as a laser mouse and laser printers. In this paper, the recent advance
of VCSEL photonics will be reviewed, which include the wavelength
extension of single-mode VCSELs and their wavelength integration/control.
Also, this paper explores the potential and challenges for new functions
of VCSELs toward optical signal processing
