中文摘要
A)光诱力(LIF)控制的光机系统动力学:阐明了振子和精确广义耦合G的稳定性条件。在良好的空腔极限下,G与防止冷却的空腔衰减率(Kappa)呈共线关系,对于小得多的kappa,它近似于kappa。计算了这些光机系统的五阶多稳态:-最低有效温度T_ff向低卡伯区移动,位于卡帕=0.03倍机械频率附近。T_ff可达数十mK,量子数可达0.01(基态振子为99%)。这表明了在极低功率下单独使用激光诱导荧光用于基态冷却的可能性,并为将其应用于量子通信开辟了一条途径。b)检测低维系统的光致发光:阐明了表面声波(SAW)泵浦的极化子的合适色散,以检测能量弛豫(SAW对色散的调制促进了这一过程)。与时间相关的量(占位数、高阶关联、线宽减小)将被检查以确认偏振激子激光(与光子激光相比)。C)利用纳米孔阵列(NHA)的等离子体能量传递:评估了LiF在具有随机尖锐金属纳米结构的NHA边缘捕获病毒的作用,并阐明了病毒可以被吸引到具有超常光传输峰的高敏感位置。
英文摘要
a) Optomechanical system's dynamics controlled by light-induced force (LIF):-stability conditions for oscillator and exactly general coupling G have been clarified. This G shows a collinear dependence on the cavity decay rate (kappa) preventing the cooling in good cavity limits and approximates to kappa for much smaller kappa. The fifth-order multistability in these optomechanical systems is figured out.-minimum effective temperature T_eff shifts to low-kappa region and locates around kappa= 0.03 X the mechanical frequency. T_eff of about several tens of mK is possible and a quantum number of 0.01 can be obtained (the oscillator is 99% in the ground state). This shows the possibility of using solely the LIF in ground-state cooling with very low power and opens a way to apply it to the quantum communication.b) Examining low-dimensional system's photoluminescence:Suitable dispersion for polaritons pumped by surface acoustic wave (SAW) is clarified to examine energy relaxation (modulation of dispersion by SAW facilitates this process). Time-dependent quantities (occupation number, high-order correlation, decrease of linewidth) will be examined to confirm the polariton lasing (vs. photon lasing). Such a simpler mechanism is promising for high temperature polariton lasing.c) Plasmonic energy transfer using nano hole array (NHA): LIF for the trapping of viruses at the edge of NHA with random sharp metallic nanostructures was evaluated and it was clarified that virus can be attracted toward the high-sensitivity position with large peak shift of extraordinary optical transmission.
