“…EDWA and Yb-co-doped EDWA performance has been investigated theoretically in a number of hosts [43,58,75,[205][206][207][208][209][210]. Such theoretical simulations are applied, for example, to select the optimum input pump power and wavelength, waveguide cross section and length, and Er concentration for a given input signal power and wavelength.…”

Erbium-doped fiber devices have been extraordinarily successful due to their broad optical gain around 1.5-1.6 μm. Er-doped fiber amplifiers enable efficient, stable amplification of high-speed, wavelength-division-multiplexed signals, thus continue to dominate as part of the backbone of longhaul telecommunications networks. At the same time, Er-doped fiber lasers see many applications in telecommunications as well as in biomedical and sensing environments. Over the last 20 years significant efforts have been made to bring these advantages to the chip level. Device integration decreases the overall size and cost and potentially allows for the combination of many functions on a single tiny chip. Besides technological issues connected to the shorter device lengths and correspondingly higher Er concentrations required for high gain, the choice of appropriate host material as well as many design issues come into play in such devices. In this contribution the important developments in the field of Er-doped integrated waveguide amplifiers and lasers are reviewed and current and future potential applications are explored. The vision of integrating such Er-doped gain devices with other, passive materials platforms, such as silicon photonics, is discussed.

“…Present study focuses on the diffusion properties of Er 3+ in an initially congruent LT crystal. The study involves Er 3+ diffusivity, solubility, their temperature dependences, as well as the Er 3+ profile characteristic, which is closely related to the optical gain of the relevant amplifier or laser [2]. The results of diffusivity and solubility are compared with the LN case.…”

“…Over the past years, a family of Ti (or vapor ZnO)-diffused Er:LN waveguide lasers (amplifiers) and (nonlinear) integrated devices have been demonstrated [1][2][3][4][5][6][7][8][9][10][11]. These devices are compact, efficient, inexpensive, manufacturable and commercially attractive, and show potential for use in a wide range including telecommunications, range finding, military counter measures, optical data storage, remote sensing and reproduction graphics [1].…”

“…Erbium doped glasses have been studied and used in a variety of photonic applications, such as infraredto-visible upconversion (UPC) infrared lasers operating in the third telecommunication window [1], and color displays and sensors [2][3][4][5]. Nevertheless, efficient pumping of this system is limited by the low absorption cross-section of Er 3+ around 980 nm that can be improved by co-doping the material with Yb 3+ ions [6][7][8].…”
