Enhancement of the quadrupole interaction of an atom with guided light of an ultrathin optical fiber
Fam Le Kien, Tridib Ray, Thomas Nieddu +2
We investigate the electric quadrupole interaction of an alkali-metal atom with guided light in the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber. We…
Pump induced lasing suppression in Yb:Er-doped microlasers
Fuchuan Lei, Yong Yang, Jonathan Ward +1
A pump source is one of the essential prerequisites in order to achieve lasing, and, in most cases, a stronger pump leads to higher laser power at the output. However, this behavio…
Optical nanofiber-based cavity induced by periodic air-nanohole arrays
Wenfang Li, Jinjin Du, Viet Giang Truong +1
We experimentally realized an optical nanofiber-based cavity by combining a 1-D photonic crystal and Bragg grating structures. The cavity morphology comprises a periodic, triplex a…
Bandpass transmission spectra of a whispering-gallery microcavity coupled to an ultrathin fiber
Fuchuan Lei, Rafino M. J. Murphy, Jonathon M. Ward +2
Tapered fibers with diameters ranging from 1-4 micron are widely used to excite the whispering-gallery (WG) modes of microcavities. Typically, the transmission spectrum of a WG cav…
Higher-order modes of vacuum-clad ultrathin optical fibers
Fam Le Kien, Thomas Busch, Viet Giang Truong +1
We present a systematic treatment of higher-order modes of vacuum-clad ultrathin optical fibers. We show that, for a given fiber, the higher-order modes have larger penetration len…
