提出了一种在耦合腔光机系统中利用可调谐光放大器实现相控超低阈值声子激光器的方案。通过设计外部参数驱动的相位和强度，各个增强的乘法行为使得有可能实现光力学的强耦合制度，其中可以实现辐射压力，参数放大和三模式光力学耦合之间的切换，并且可以观察到超低阈值声子激光。这为量子声学、非线性声子器件和超灵敏运动传感等领域的应用开辟了新的前景。
A phase-controlled ultralow-threshold phonon laser is proposed by using tunable optical amplifiers in coupled-cavity-optomechanical system. The multiplicative behavior of the individual enhancements, by engineering the phases and strengths of external parametric driving, makes it possible to achieve the strong-coupling regime of optomechanics, where the switching among radiation-pressure, parametric amplification, and three-mode optomechanical couplings can be realized and ultralow-threshold phonon lasing is observable. This opens up novel prospects for applications in, e.g. quantum acoustics, nonlinear phonon devices, and ultrasensitive motion sensing.
