摘要/Abstract

摘要： 研究了Bose-Einstein凝聚(BEC)腔光力学系统中的相干完美吸收现象，阐述了诱导相干完美吸收产生的条件，分析了强耦合BEC光力学腔发生相干完美吸收时的能量转换。通过控制泵浦场功率可以有效调制相干完美吸收。当相干完美吸收产生时，输入探测场能量完全转化为机械振子和腔场能量而不产生任何透射和反射,并且通过改变腔的品质因子Q可实现能量萃取。强耦合BEC腔光力学系统为基于相干完美吸收的换能器、调制器及光开关等潜在应用提供了理论基础。

Abstract: The coherent perfect absorption phenomenon in cavity optomechanics system with Bose–Einstein condensation(BEC) is investigated. The conditions of inducing coherent perfect absorption producing are elaborated, and the energy conversion is analyzed when coherent perfect absorption occurs in strong coupled BEC cavity optomechanics system. Coherent perfect absorption can be effectively modulated by controlling the pump field power. When coherent perfect absorption occurs, the input probe field energy is completely converted into the mechanical oscillator and cavity field energy without any transmission and reflection. Energy extraction can be realized by changing the cavity quality factor. The strong coupled BEC cavity optomechanics system provides a theoretical basis for potential applications based on coherent perfect absorption, such as transducers, modulators, and optical switches and so on.

Key words: quantum optics; Bose–Einstein condensate; cavity optomechanics system; coherent perfect absorption
