In this paper we review the main results on slow and fast light induced by coherent
population oscillations in optical fibres doped with erbium ions. We explain the physics …

In connection with the experiments recently achieved on doped crystals, biological samples,
doped optical fibers, and semiconductor heterostructures, we revisit the theory of the …

A high-sensitivity gyroscope is vital for both investigation of the fundamental physics and
monitor of the subtle variation of Earth's behaviors. However, it is challenge to realize a …

Quantitative analysis of slow light experiments utilising coherent population oscillation

We experimentally and theoretically study the propagation of a 1536 nm light pulse
superposed on a continuous wave background in a highly doped erbium fiber pumped at …

We analyze the propagation regime of an amplitude-modulated 1536 nm signal when
traveling along a highly doped erbium fiber pumped at 977 nm as a function of the fiber …

We report on the control of the slow and fast light propagation velocity of two light beams (at
1550 nm and 980 nm) through an erbium-doped fibre amplifier by means of coherent …

We study slow-light performance of molecular aggregates arranged in nanofilms by means
of coherent population oscillations. The molecular cooperative behavior inside the …

We report a change from sub-to superluminal propagation upon increasing the modulation
frequency of an amplitude-modulated 1550 nm signal when propagating through highly …

We report controllable (slow or fast) propagation of low-intensity probe-light pulses through
erbium-doped fiber periodically saturated by the synchronized master-pulse sequence …
