27 Nov 2006 A new series of fluorophosphate glasses (MBBA System) doped with Er(III) were introduced for use in broadband compact optical fibers, compact waveguide amplifiers, and compact fiber lasers. These glasses were developed by AFO Research, Inc. (AFO) and tested at the University of California, Irvine (Dept. of Chemical and Material Science, and Department of Chemistry). The tests showed that these fluorophosphate glasses exhibit higher spectroscopic quality factor (Q value) whereas Q=1.62 (Q=omega4/ omega6) than other commercial available optical glasses. For example, the Q value of BK20 is Q=1.56, ZBLAN is Q=1.54, Phosphate is Q=1.34, and FP20 is Q=0.99. These results further confirm that AFO’s fluorophosphate glasses are better candidates for laser host materials than the leading commercially available glasses in the marketplace today. The strong emission bands were observed at 1536 nm and the effective bandwidths were found to be 91 nm, which is the widest bandwidth achieved amongst any commercial laser glasses available today.
In conclusion, the combination of outstanding spectroscopic and optical properties demonstrated in AFO’s Er (III) doped fluorophosphate glasses proves that they are excellent materials for the development of next generation advanced compact optical and optoelectronic devices.
