    • n Erbium (Chem) A rare earth element of the lanthanide series associated with several other rare elements in the mineral gadolinite from Ytterby in Sweden. Symbol Er. It has atomic number 68 and an atomic weight of 167.26. The pure element is metallic with a bright, silvery luster. It is relatively stable in air, not oxidizing as quickly as some other rare earths. Its salts are rose-colored and give characteristic spectra, and the pink oxide has been added as a colorant in glass and porcelain enamel glazes. Its sesquioxide Er2O3 is called erbia.

Octave Spanning Frequency Comb on a Chip
The experimental setup for octave spanning frequency comb generation in a toroidal microresonator is depicted in Figure 1a and consists of an external cavity diode laser (ECDL) that is amplified by an erbium doped fibre amplifier (EDFA) to an output power of up to 2.5 W.

Universal cloning (first column), which clones all possible qubits with equal fidelity, can be realized with a simple optical amplifier, e.g. an erbium doped fiber amplifier .
Cloning Entangled Qubits to Scales One Can See
Universal cloning necessarily comes with additional quantum systems, called anti-clones; in the mentioned example the additional systems are the erbium ions.
Cloning Entangled Qubits to Scales One Can See
In fact any phase invariant amplifier, such as an Erbium doped fibre amplifier (EDFA), can be used as a universal cloning machine.

Revival of Silenced Echo and Quantum Memory for Light
The two-level model of atoms is a simplified approach that can be applied to actual lasers based on three-level atoms such as Ruby and Erbium lasers, as the population in the third level is negligibly small .
Inherent Stochastic Linearization of Random Laser Modes
The third window is around 1550 nm where the attenuation reaches an absolute minimum (Thomas et al. 2000) and where erbium doped fibers provide convenient amplifiers (Desurvire 1994). 23Chromatic dispersion in fibers is mainly due to the material, essentially silicon, but also to the refractive index profile.
Quantum Cryptography
The additional loss is then compensated by an erbium doped fiber amplifier. 24Assuming a predominantly linear dependence of CD in function of the optical frequency, a realistic assumption.
Quantum Cryptography
The most common type is the erbium doped fiber laser that emits within the telecom band around 1550 nm.
