Wavelength-sized microcavity lasers have very unique and attractive features; One is a threshold-less lasing action, and the other is an ultrafast response capability. The latter property comes from the extremely short cavity round-trip time and the resulting short photon life time of the microcavity. The 100 Gbit/s response of a dye-solution planar microcavity laser has been demonstrated under an quasi-optical-pulse-train excitation.
