“…Our work and system are mainly based on the Refs. [7][8][9][10][11][12][13][14][15][16][17], however our scheme is different from those works. First, the rare-earth-ion-dope optical-fiber system is much more practical than its atomic counterpart due to its flexible design and the wide adjustable parameters.…”

“…Apart from solid-state quantum well nanostructures, EIT has been observed for rare-earthdoped crystals, such as Pr 3 :Y 2 SiO 5 [49]. Efficient EIT in such solid crystals opens potential applications, such as light storage [50], large refractive index without absorption [51], and coherent control of OB [52]. The generation of twin beams by the parametric amplification four-wave-mixing process and triplet beams by the parametric amplification six-wave-mixing (PA SWM) process associated with the multiorder fluorescence signals in a Pr 3 :Y 2 SiO 5 crystal has been also reported [53].…”

Optical bistability forming due to a Rydberg state

We consider the behavior of optical bistability (OB) and multistability (OM) in a four-level atomic system involving a Rydberg state illuminated by a probe field as well as control and switching laser beams of larger intensity. When the switching field is absent, no OB arises because of the effect of Rydberg electromagnetically induced transparency. However, by application of the switching field, the hysteresis cycle appears to give rise to optical bistability, thanks to Rydberg electromagnetically induced absorption. It is further demonstrated that one can efficiently modify the OB threshold via suitable choices of system-controlling parameters. Interestingly, it is observed that this model can produce an optical switching between OB and OM with potential applications in logic-gate devices for optical communication.

“…On account of the flexible design and adjustable parameters comparing to their atomic counterparts, the E 3+ r -doped optical fiber systems play a more important role in practical application for quantum optics. And some nonlinear quantum optical phenomena, such as gain leveling [13], optical bistability and multi-stability [14], absorption-amplification response [15], enhanced index of refraction with vanishing absorption [16] were achieved in * Corresponding author: zhaosc@kmust.edu.cn…”

The left-handedness was demonstrated in an E 3+ r -dopped ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAFN) optical fiber modeled by a three-level quantum system. Under the electric and magnetic components of the probe field driving the transitions of 4 I 15/2 -4 I 13/2 and 4 I 9/2 − 4 I 13/2 in the E 3+ r -dopped optical fiber respectively, an increasing left-handedness was achieved by the incremental incoherent pumping field. However, the left-handedness damped when the incoherent pumping field drove the transition heavily. Our scheme may provide a solid candidate other than the coherent atomic vapour for left-handedness, and may extend the application of the rare-earth-ion-doped optical fiber in metamaterials via the external incoherent pumping field.
