提出了一种利用耦合到波导的光子分子光机系统产生可调谐高阶边带谱的方案。该系统由一个连续波控制场和一个脉冲驱动场组成的双音激光器通过波导进行相干驱动。通过数值模拟分析了输出光场的频谱特性，证实了在纳秒级强脉冲驱动下，输出光场具有高阶边带频谱特性。在实验可得的参数范围内，通过改变驱动脉冲功率和腔间耦合率等系统参数，可以有效地调谐输出光谱。此外，高阶边带产生的载波包络相位相关效应的分析表明，该系统可能存在依赖于脉冲的相位。这为进一步了解非线性和非微扰状态下的腔光力学性质提供了新的思路，并在基于光力学平台的光频梳和光通信中具有潜在的应用价值。
A tunable high-order sideband spectra generation scheme is presented by using a photonic molecule optomechanical system coupled to a waveguide beyond the perturbation regime. The system is coherently driven by a two-tone laser consisting of a continuous-wave control field and a pulsed driving field which propagates through the waveguide. The frequency spectral feature of the output field is analyzed via numerical simulations, and we confirm that under the condition of intense and nanosecond pulse driving, the output spectrum exhibits the properties of high-order sideband frequency spectra. In the experimentally available parameter range, the output spectrum can be efficiently tuned by the system parameters, including the power of the driving pulse and the coupling rate between the cavities. In addition, analysis of the carrier-envelop phase-dependent effect of high-order sideband generation indicates that the system may present dependence upon the phase of the pulse. This may provide a further insight of the properties of cavity optomechanics in the nonlinear and non-perturbative regime, and may have potential applications in optical frequency comb and communication based on the optomechanical platform.
