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.
