原子薄的二维半导体纳米材料目前已经引起了相当大的关注。在这里,我们提出了一种基于悬浮单层二硫化钼(MoS_2)的纳米光机械系统。证明了该系统的线性和非线性相干光学性质,以及声子诱导透明现象。探测场的传输可以通过第二个选通(泵浦)场的功率来控制,这表明有希望成为光学晶体管的候选者。我们进一步研究了系统的非线性效应,单层MoS_2腔的光克尔效应可以在不同的参数范围内调节。这一方案可能预示着单层MoS_2谐振器与当前流行的泵浦-探测技术在量子信息中的潜在芯片规模的应用。
Atomically thin two-dimensional semiconductor nanomaterials have attained considerable attention currently. Here, we present a nano-optomechanical system based on a suspended monolayer molybdenum disulfide (MoS2). The linear and nonlinear coherent optical properties of this system, and the phenomenon of phonon-induced transparency are demonstrated. The transmission of the probe field can be manipulated by the power of a second ‘gating’ (pump) field, which indicates a promising candidate for an optical transistor. We further study the nonlinear effect of the system, and the optical Kerr effect of the monolayer MoS2 resonator can be regulated under different parameter regimes. This scheme proposed here may indicate potential chip-scale applications of monolayer MoS2 resonator in quantum information with the currently popular pump-probe technology.
