We investigate tunneling induced nonlinear absorption phenomena in a coupled quantum-dot system. Resonant tunneling causes constructive interference in the nonlinear absorption that leads to an increase of more than an order of magnitude over the maximum absorption in a coupled quantum dot system without tunneling. Resonant tunneling also leads to a narrowing of the linewidth of the absorption peak to a sublinewidth level. Analytical expressions show that the enhanced nonlinear absorption is largely due to the fifth-order nonlinear term. Competition between third- and fifth-order nonlinearities leads to an anomalous dispersion of the total susceptibility.

“…EIG initially was proposed in a Λ-type threelevel atomic system [1], then experimentally demonstrated in cold and hot atomic media [2][3][4]. The great attention to EIG is due to its potential applications in significant fields such as all-optical switching and routing [2], probing material optical properties [4], atomic/molecular velocimetry [5], light storage [6,7], optical bistability realization [8], beam splitting and fanning [9], shaping a biphoton spectrum [10], developing novel photonic devices in semiconductor QW systems [11], and controlling multi-wave mixing signals via photonic band gap of electromagnetically induced absorption grating in atomic media [12]. It is shown that the intensity of higher-order diffractions could be enhanced in a three-level ladder type system [13].…”

A new scheme for investigating electromagnetically induced grating in four-level cascade-type of 87Rb cold atoms is presented. The novel result indicates that the diffraction efficiency of phase grating is dramatically enhanced due to the presence of an RF-driven field and a diffraction efficiency up to 34% can be obtained. Furthermore, it is found that the frequency detuning of the applied laser fields with the corresponding atomic transition and the interaction length can improve the efficiency of the phase grating in the present atomic model. This work has potential applications in all-optical communication processes.

“…While for EIT, the coherence depends on external-field coupling. TIT has been widely used for ultrafast switch [22], enhanced Kerr nonlinearity [23,24], optical grating [25], wavelength selection [26] and separating optical precursors [27]. Tunneling-coupled two adjacent QDs form a QD molecule (QDM) [28].…”
