Tunable, Single-Frequency, Fiber Fabry-Perot VCSELs

The figure depicts several aspects of a unique type of vertical-cavity surface-emitting lasers (VCSELs) that incorporate fiber Fabry-Perot (FFP) optical cavities. These lasers have been designed to be compact, compatible with optical fibers, capable of single-frequency operation, and tunable. Lasers of this type that operate in frequency bands centered at wavelengths of about 850 and about 1,300 nm have been demonstrated.
