Abstract

HRTEM image showing nano-silicate formation in a glassy matrix, after annealing at 1000 oC for 24 hours


Invention Summary:

A new class of nanostructured RE-doped SiO2-base materials that display superior fluorescence properties with high gain combined with a broad and flat spectral band with. Such enhanced fluorescence properties have been observed in heat treated nanopowders prepared by vapor-phase, sol-gel and spray-pyrolysis methods. The expectation is that similar effects will be observed in monolithic materials, when known bulk glass processing methods, such as glass-ceramic processing, incorporate an intermediate heat treatment step to generate preferred nanocomposite structures.

Market Application:

In addition to optical amplifiers and tunable lasers, other potential applications for nanophotonic ceramics include 3-color displays, sensors optical switches and modulators, splitters and couplers, isolators and filters.

Advantages:

Enhanced florescent properties, making the material particularly suitable for high bandwidth erbium-doped fiber amplifiers (EDFA’s).
