Abstract

Cerium and bismuth have been successfully incorporated into (HoYb) _3-x-yCe_xBi_yFe₅O₁₂ iron garnets with up to x=0.164 and y=0.665 by using the Bi₂O₃ self-flux growth technique. The (HoYb)_2.171Ce_0.164Bi _0.665Fe₅O₁₂ crystal has exhibited a much higher specific Faraday rotation of -1035 deg/cm and an equivalent absorption coefficient of 2.18 cm^-1 at 1550 nm as compared with those of -588 deg/cm and 1.84 cm^-1 for (HoYb)_2.501Bi _0.499Fe₅O₁₂. The mixed effect of Ce ³⁺ and Bi³⁺ ions on the Faraday rotation has been analyzed qualitatively. In addition, due to the incorporation of Ce, the Faraday-rotation wavelength and temperature coefficients for (HoYb) _2.171Ce_0.164Bi_0.665Fe₅O ₁₂ are higher than those for (HoYb)_2.501Bi _0.499Fe₅O₁₂ at 1550 nm. Despite this, (HoYb)_3-x-yCe_xBi_yFe₅O₁₂ has a great potential for application in 1550-nm optical isolators due to its large figure of merit of 109 deg/dB.
