Adiabatic Population Transfer Based on a Double Stimulated Raman Adiabatic Passage

Abstract

Stimulated Raman adiabatic passage (STIRAP) is an adiabatic population-transfer technique that uses two coherent laser pulses in counter-intuitive order, namely, pump and stoke, to achieve complete transfer between two quantum states. Here, we propose a double STIRAP scheme whereby the electronic levels of a four-level atom are coupled by three laser fields forming two pairs of stoke and pump pulses. We derive the optical Bloch equations through the master equation for studying the population dynamics. We show that manipulating the time between two STIRAP sequences provides the state transfer near unity. In particular, we show that there occurs a certain maximum transfer efficiency that can be achieved in the double STIRAP process.

Optomechanically induced transparency in multi-cavity optomechanical system with and without one two-level atom

“…It usually composed of two mirrors with one fixed and the other movable or a micro-mechanical membrane oscillating inside two fixed mirrors. Such a system demonstrates the interaction between the movable oscillator and the optical field in the cavity via the radiation pressure and becomes a platform for the study 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 of quantum ground-state cooling 17 18 19 20 , strong coupling dynamics 1 7 21 22 and other coherent dynamics in microscopic and macroscopic domains 23 24 25 . When a strong laser field drives the optomechanical cavity, an analogue of electromagnetically induced transparency (EIT) for the output at the frequency of the weak detecting field could appear 26 27 .…”

Tunable subluminal and superluminal light with optomechanical-induced transparency under steady-state configuration

“…Parallel to the phenomenon of perfect absorption in linear dielectrics [8][9][10][11], a phenomenon known as inverse EIT in an optomechanical system is also reported in which the light is completely confined in the cavity with no output field [12]. Other related optical phenomenon that can be explored in the context of optomechanical system include stimulated Raman adiabatic passage [13][14][15], refractive index enhancement [16][17][18], Fano resonances [3,19,20] and nano-optic resonators [21]. When a cavity is driven by a strong pump field, the coupling of its modes with mechanical resonator can be increased, and the rate of such increase depends on the average photon number in the cavity [22].…”

“…Since OIT is one of characteristic traits of a cavity optomechanical system [15,35], this work intends to investigate how this characteristic property and the dynamics of other related quantities of a two-cavity optomechanical system changes when an additional degree of freedom in the form of a two-level atom is coupled to one cavity of the system. Our results show that such a change in the configuration considerably modifies the collective dynamics of the system.…”

Multiple electromagnetically induced transparency, slow and fast light in hybrid optomechanics

“…Since its experimental realization [9,10], EIT has made valuable contributions in the development of optical sciences because of its promising applications in multidisciplinary fields [11][12][13][14][15]. For instance, EIT has appeared as fundamental ingredient for the real applications like group velocity control [16][17][18], nonlinear susceptibility modulation [19], quantum information processing [2,5], quantum metrology [5,7], dark-state polariton [20], induced photon-photon interaction in cold atomic gases [2], Rydberg atomic-state detection [21,22], cavity linewidth narrowing [23] and laser frequency stabilization [24].…”
