“…Taking advantage of fiber-coupled configuration, the SPPs are derived from the gold nanowires deposited in the D-shaped photonic crystal fiber (PCF) surface, and interacted with the above quantum emitter. They can lead to the quantum interference between the spontaneous emission transition channels, and modify the spontaneous emission spectrum and affect population dynamics of the corresponding levels [32,33]. As a result, the effects of Rabi frequency (Ω c ) of the coupled field and quantum interference (q) associated with the SPPs on the MOR angle and magnetic field sensitivity are numerically analyzed.…”

We propose a kind of surface plasmon polaritons (SPPs)-assisted dual-V-type four-level composite system used for high-sensitivity weak magnetic field measurement. The SPPs are excited by a D-shaped photonic crystal fiber (PCF) deposited with gold nanowires, and are interacted with the above quantum emitter from the rubidium atomic vapor. In the presence of the external magnetic field, Faraday rotation symmetry is broken due to Zeeman effect, resulting in the polarization plane rotation when a linearly polarized probe field goes through the above quantum emitter. With the help of the coupled field and SPPs, Faraday magneto-optical rotation (MOR) are effectively regulated. The Rabi frequency of the coupled field (Ω c ), quantum interference degree (q), and phase difference (φ) between the applied fields show strong dependence on the MOR angle and magnetic field measurement sensitivity. The simulated results reveal that the maximum MOR angle and magnetic field sensitivity both damp with Ω c expanding and q reducing. The maximum dichroism-independent MOR angle of 89.97° is realized for φ = 0° (180°), and the magnetic field sensitivity of 10.88°/Oe is obtained in the sweeping range of −8.88–8.88 Oe for q = 0.99, being 2.66°/Oe higher than that in the absence of SPPs (q = 0). Most importantly, the output probe field with different polarization forms can be realized by adjusting the φ value. Hence, the proposed device exhibits the potential in the fields of weak magnetic field measurement and polarization control.

“…It was shown that the spontaneous emission spectrum in the free space mode is affected by the presence of a plasmonic nanostructure. Talkhabi and Mortezapour investigated magneto optical rotation (MOR) in a four-level atomic system in the presence of a plasmonic nanostructure [40]. They realized that in the presence of a plasmonic nanostructure, MOR can occur for a small magnetic field.…”

We study the optical properties of a coupled quantum dot (QD)-metallic nanoparticle (MNP) hybrid system via a quantum mechanical density matrix method. The QD system is considered as a three-level V-type configuration and is interacted with a weak probe light and a strong coupling light. The QD is placed near the MNP system and therefore the transition is interacted with a probe laser located near to the frequency of the MNP. We realize that due to the radius of the MNP and surface plasmon effects, the distance between the QD and MNP can optimize the absorption, dispersion, and group index of the hybrid system. We find that the probe amplification without population inversion can be obtained with a suitable distance between the QD and MNP. Moreover, a tunable superluminal light propagation is obtained for some parametric conditions of the hybrid system.
