【摘要】：研究了基于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]:Study on the aggregation of Bose-Einstein (BEC) coherent optical cavity perfect absorption phenomenon in the mechanical system, expounds the perfect absorption induced coherence conditions, analysis of the strong coupling BEC power, the cavity has perfect absorption of coherent energy conversion. The coherent perfect absorption can be effectively modulated by the control of the pump field power. When coherent perfect absorption is generated, the energy of the input field is completely transformed into the mechanical oscillator and the cavity field energy without any transmission and reflection, and the energy extraction can be realized by changing the quality factor of the cavity. The strong coupled BEC cavity photodynamic system provides a theoretical basis for potential applications, such as transducer, modulator and optical switch based on coherent and perfect absorption.
