Uniform upconversion in erbium-doped silicate glasses is investigated as a function of glass composition, concentration, and fabrication method. Comparisons of upconversion coefficients are made among soda lime silicate and aluminosilicate bulk glasses and soda lime silicate waveguides. Comparisons are also made with studies performed by other researchers. The results indicate that both the composition and the preparation method of the glass affect the value of the upconversion coefficient, with as much as a factor-of-4 variation observed at fixed Er{sup 3+} concentration. Values of the upconversion coefficient are found to be consistent with the F{umlt o}rster{endash}Dexter microscopic model. {copyright} {ital 1997} {ital Optical Society of America}
