Light pulse group velocity manipulations due to the specific dispersion of a medium (so-
called “slow” and “fast” light phenomena) can be obtained on the basis of several …

The propagation of a weak-field pulse through a medium of three-level atoms is considered.
Each atom has a Λ-type level scheme in which the two lower levels are stable. A strong …

We study the green upconversion luminescence of Er 3+ ions in an aluminosilicate optical
fiber upon near infrared excitation at 787 nm. The dependence of the upconversion …

Experimental results on effective two-wave mixing (TWM) via dynamic population gratings in
saturable erbium doped fibers (EDFs) at liquid nitrogen temperature (77 K) are reported. It is …

This thesis provides a spectroscopic study on the relevant properties of Erbium-doped
Optical Fiber (EDF) for its application as a light-matter interface in large-scale quantum …

Metamaterials, which are materials engineered to possess novel optical properties, have
been increasingly studied. The ability to fabricate metamaterials has sparked an interest in …

Spectral hole-burning in an erbium-doped silica fibre at room temperature has been
experimentally demonstrated. This demonstration can be considered as a clear …
