Rabi Frequency and Oscillation in a Nonlinear Micro-ring Circuit

Abstract

Rabi oscillation has been observed in many super-conducting devices, in which the quantum
behavior between atom and electromagnetic field interaction is occurred. In this paper, we use an average
two-level transient atom within the micro-ring resonator, which is consequently generated by the
AlGaAsmaterial interaction with the electromagnetic field in time-domain. The simulation results obtained
have shown that the coupling intensity is affected to the output intensity oscillation and also directly
affected to the Rabi frequency. The probability to find atom in the excited state of the device with the
reducing frequency at resonance is also calculated, in which the probabilities of 0.85 and 0.20 are
obtained for resonance and non-resonance states, respectively. The Rabi frequency oscillation in the
range of terahertz is obtained, which can be useful for atom antenna and sensing applications.
