摘要:

利用成熟的电信光子平台控制中红外(MIR)光子将为分子和量子光子学带来新功能。然而,由于MIR和电信光子之间巨大的光谱间隔和弱的非线性耦合,建立它们之间的高效相互作用仍然具有挑战性。在这里,我们展示了由振动极化激元介导的MIR光子的光机械控制,实现了跨遥远光谱区域的MIR和电信场之间的光子-光子相互作用。通过使用包含振动活性聚合物的法布里-珀罗腔,我们观察到在4 mW泵浦下,电信驱动的MIR光子(9.5 μm)的耗散增强,调制深度为1%。线性功率依赖性、混合比依赖性和失谐响应一致表明,通过强光-物质耦合实现了MIR和电信光子-光子转换。该方法建立了一个用于桥接不同光谱区域的极化激元光机械平台,并为混合MIR光子学和量子转换提供了一条耗散工程路线。

英文摘要:

Controlling mid-infrared (MIR) photons using well-developed telecom photonic platforms would enable new functionalities in molecular and quantum photonics. However, establishing efficient interactions between MIR and telecom photons remains challenging due to their large spectral separation and weak nonlinear coupling. Here, we demonstrate optomechanical control of MIR photons mediated by vibrational polaritons, enabling photon-photon interaction between MIR and telecom fields across distant spectral regions. Using a Fabry-Pérot cavity incorporating a vibrationally active polymer, we observe telecom-driven dissipation enhancement of MIR photons at 9.5 $μ$m with a modulation depth of 1% under a 4 mW pump. The linear power dependence, mixing-ratio dependence, and detuning response consistently indicate a MIR and telecom photon-photon conversion enabled by strong light-matter coupling. This approach establishes a polaritonic optomechanical platform for bridging disparate spectral regimes and provides a dissipation-engineered route toward hybrid MIR photonics and quantum transduction.
