,1.3 and 1.55 μm Vertical-Cavity Surface-Emitting Lasers, emission wavelength near 850 nm), printers (in the visible region), compact disk players (near 780 nm) and many other systems. VCSELs may also find many applications in data communication and telecommunication systems (at 1.3 μm and 1.55 μm); however, they are not yet available commercially in this

Long-Wavelength InP-Based VCSELs,ent years . This is particularly due to the intrinsic advantages of this laser type as compared to the edge-emitting laser diodes. The most important features of VCSELs are their low beam divergence leading to relaxed fiber alignment tolerances, the sub-milliamp threshold current and high slope e

1437-0379 aser (VCSEL) is a relatively new se- conductor laser device, especially applicable to ?ber-optic networks in the 21st century. About 25 years have passed since its invention, and devices for Gigabit Ethernet are now being mass-produced. It is expected that VCSELs will open up a new era of very-high-

,1.3 and 1.55 μm Vertical-Cavity Surface-Emitting Lasers, wavelength range. These wavelengths are of great interest for the transmission of information over fibers. Longer distances and higher speeds dictate the move toward these wavelengths, which correspond to the minimum dispersion and minimum loss in standard glass fiber at 1.3 and 1.55 μm, respectively.
