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…
