基于相位调制的非互易反射光放大动力学调控
Dynamical manipulation of non-reciprocal reflected light amplification based on phase modulation
摘要
Abstract
The development of new photonic devices based on optical non-reciprocity is crucial for information processing.As information tends to be weakened during transmission,achieving amplified optical signals is a major focus of scientific research in this field.This paper proposes a simple regime to achieve amplified non-reciprocal reflection.Firstly,a strong coupling field and a microwave field are used to control a weak probe field to form a three-level coherent atomic system,enabling the detection light signal to be amplified at the transparent window.Then,the symmetry of probe susceptibility is broken utilizing the linear variation of coupling field,leading to the realization of non-reciprocal light reflection amplification.Finally,the amplification range of non-reciprocal reflection bands is modulated by adjusting the relative phase between laser fields.The numerical results demonstrate that in the nonreciprocal frequency domain,when the relative phase is Φ=0,π,and 3π/2,only one reflection band is amplified.However,when the relative phase reaches Φ=π/2,two non-reciprocal reflection bands are amplified simultaneously with a magnification range of 1.25-1.75 times.It is shown that the proposed regime can achieve dynamic manipulation of non-reciprocal reflection.关键词
