摘要:

我们展示了由一个χ 2非线性光子晶体纳米腔介导的可调谐频率转换光。波长尺度的InP基腔支持两个近1550 nm附近的近间隔的本地化模式由130 fs的激光脉冲共振激发。腔体同时照射的非共振探测光束,产生丰富的二阶散射光谱,反映不同的共振和非共振成分的非线性混合。特别是,我们突出的探测光束和各自的腔模式的和频率的辐射。这将是一个有用的,微创监测的联合占用状态的多个腔在集成光路。

英文摘要:

We demonstrate tunable frequency-converted light mediated by a chi-(2) nonlinear photonic crystal nanocavity. The wavelength-scale InP-based cavity supports two closely-spaced localized modes near 1550 nm which are resonantly excited by a 130 fs laser pulse. The cavity is simultaneously irradiated with a non-resonant probe beam, giving rise to rich second-order scattering spectra reflecting nonlinear mixing of the different resonant and non-resonant components. In particular, we highlight the radiation at the sum frequencies of the probe beam and the respective cavity modes. This would be a useful, minimally-invasive monitor of the joint occupancy state of multiple cavities in an integrated optical circuit.
