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…
All-Optical Nanopositioning of High-Q Silica Microspheres
Rafino M. J. Murphy, Fuchuan Lei, Jonathan M. Ward +2
A tunable, all-optical, coupling method has been realized for a high-\textit{Q} silica microsphere and an optical waveguide. By means of a novel optical nanopositioning method, ind…
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…
