Enhanced 1.53-μm emission and lowered upconversion of Er3+-doped gallate–lead–bismuth–germanium glass by rare-earth co-doping

Visible, Up-conversion and NIR (~1.5μm) luminescence studies of Er3+ doped Zinc Alumino Bismuth Borate glasses

“…The Ω 4 and Ω 6 JO parameter values depend on the bulk properties of the medium such as viscosity and dielectric constant of the media and are also affected by the vibronic transitions of the RE ions bounded to the ligand atoms [36][37][38]. As given in Table 3, the JO parameter values obtained for the present glass systems are comparable with the values reported for other Er 3+ doped glassy systems [26,[39][40][41][42][43][44][45][46][47].…”

“…Such materials are very important because of their versatile applications in diversified fields such as fibre amplifiers, optoelectronic devices, lasers, colour displays, optical data storage and under water optical communication [1]. In recent year's wavelength division multiplexing (WDM) technology gained so much of attention as it increases the information carrying capacity of communication network used in telecommunication systems [2][3][4]. Since broadband fibre amplifiers are the key devices in such systems, tremendous work has been dedicated in fabricating the optical materials possessing broad bandwidths of luminescence particularly in the wavelength range from 1200-2600 nm [5,6].…”

“…For such near infrared and mid infrared applications, the materials in general are activated by rare earth (RE) ions. Quite recently, RE ions doped glasses are found to be potential in the development of luminescent devices suitable for Infrared (IR) lasers, infra-red to visible up-convertors, fibre and waveguide amplifiers for optical transmission network [2][3][4].…”

Luminescence Properties of Er³⁺-Doped Ga₂O₃-GeO₂-Bi₂O₃-R₂O (R=Na and K) for 1.53 μm Fiber Amplifier

“…Therefore various glasses have been extensively investigated as hosts in order to realize high efficiency and broadband operation in Er 3+ -doped fiber amplifier (EDFA) [4][5][6]. Currently silica-based EDFAs are key devices for wavelength division multiplex (WDM) technology because it could be used to realize an efficient, low-noise amplification of light in the third optical fiber communication window [3]. However, there exist some disadvantages in silica-based EDFAs, such as low-doped concentration, narrow amplification bandwidth and non-uniform gain spectrum etc [7].…”
