Optical bistability in Er-Yb co-doped phosphate glass microspheres at room temperature
J. M. Ward, D. G. O'Shea, B. J. Shortt +1
We experimentally demonstrate optical bistability in Er3+-Yb3+ phosphate glass microspheres at 295 K. Bistability is associated with both Er3+ fluorescence and lasing behavior, and…

Upconversion channels in Er3+:ZBLALiP: multicolour microspherical light source
Danny G. O'Shea, Jonathan M. Ward, Brian J. Shortt +3
We present results on the realization of an all-taper coupled, multicolour microspherical glass light source fabricated from the erbium doped fluoride glass ZBLALiP. Whispering gal…

A heat-and-pull rig for fiber taper fabrication
J. Ward, D. O'Shea, B. Shortt +3
We describe a reproducible method of fabricating adiabatic tapers with 3-4 micron diameter. The method is based on a heat-and-pull rig, whereby a CO2 laser is continuously scanned…
