Er3+ doped glasses: Correlating the glass composition with spectroscopic properties and with the local symmetry of the Er site

Structural and spectroscopic studies of Er3+ in different fluorophosphate glasses for green laser and fibre amplifier operations

“…The PL band exhibited asymmetric shape at ∼1534 nm. Due to the selection rules compliance ΔS = ΔL = 0, and ΔJ = ±1 this transition would in grain electric and magnetic dipole parts [38][39][40]. When the samples were excited at 980 nm, the Er 3+ ions will go to 4 I 11/2 level, thereby they eventually decay non-radiatively to the next lower energy level 4 I 13/2 .…”

New Er3+ doped antimony oxide based glasses: Thermal analysis, structural and spectral properties

“…Rare earth (RE) doped glasses have been key materials for the telecommunication industry, and RE ions such as Er 3+ have attracted much interest as luminescence centers in crystals and glasses. Currently, special attention is given to the erbium ion due to its emission band at 1.53µm [12][13][14][15][16][17][18][19][20][21][22], which makes it an ideal component for applications in the field of optical data transmission. However, we realize that these oxide glasses, including borate, phosphate and silicate, specifically, have some limits.…”

Amplifying characteristics Er-doped chalcogenide glass

“…Stakla dopirana retkim zemaljama nalaze široku primenu u telekomunikacijama i optoelektronici, a očekuje se njihov sve veći i brži razvoj [1]. Opsežna istraživanja su pokazala da su halkogenidna stakla, zbog velike transparencije u IC oblasti spektra i velikih vrednosti indeksa prelamanja veoma pogodna kao matrični materijali za dopiranje jonima retkih zemalja.…”

“…Upotreba halkogednih stakala dopiranih Er 3+ , kao pojačavača zasniva se na njegovim 4f prelazima koji se nalaze u "c-band" oblasti talasnih dužina, a to je oblast između 1530 i 1560 nm [1]. Prodor u ove oblasti talasnih dužina je od velikog značaja u optoelektronici i smatra se da će halkogenidna stakla dopirana retkim zemljama preuzeti vodeću ulogu optičkih pojačavača, kao što je u doba razvoja elektronike imao tranzistor [1].…”
