摘要:

在纳米光子学中,宽可调谐相干源对于从通信到传感的众多应用而言是必需的。中红外光谱区域(波长超过2 μm)对于依赖分子光谱学的应用尤为重要。在可调谐源中,光学参量振荡器通常提供一些最宽的调谐范围;然而,它们在纳米光子学中的实现仅限于窄调谐范围,且仅局限于可见光和近红外波长。在此,我们在色散工程的周期性极化铌酸锂纳米光子学中超越了这些限制,并展示了超宽可调谐的光学参量振荡器。在泵浦波长接近1 μm的情况下,我们在单个芯片上生成了从1.53 μm到3.25 μm可调谐的输出波长,输出功率高达数十毫瓦。我们的结果代表了纳米光子学中首个延伸到中红外的倍频程可调谐源,这对于众多集成光子学应用可能是有用的。

英文摘要:

Widely-tunable coherent sources are desirable in nanophotonics for a multitude of applications ranging from communications to sensing. The mid-infrared spectral region (wavelengths beyond 2 $μ$m) is particularly important for applications relying on molecular spectroscopy. Among tunable sources, optical parametric oscillators typically offer some of the broadest tuning ranges; however, their implementations in nanophotonics have been limited to narrow tuning ranges and only at visible and near-infrared wavelengths. Here, we surpass these limits in dispersion-engineered periodically-poled lithium niobate nanophotonics and demonstrate ultra-widely tunable optical parametric oscillators. With a pump wavelength near 1 $μ$m, we generate output wavelengths tunable from 1.53 $μ$m to 3.25 $μ$m in a single chip with output powers as high as tens of milliwatts. Our results represent the first octave-spanning tunable source in nanophotonics extending into the mid-infrared which can be useful for numerous integrated photonic applications.
