非线性和集成光子学的结合使克尔频率梳在稳定的基于芯片的微谐振器中产生。这种梳状系统将彻底改变应用，包括多波长激光、计量学和光谱学。砷化铝镓（AlGaAs）具有很高的材料非线性和较低的非线性损耗。然而，器件加工困难和器件有效非线性低，使得克尔频率梳的产生难以实现。在这里，我们展示了绝缘体上的algaas作为电信波长的非线性平台，具有超高的器件非线性。我们展示了高质量因子（Q bbb10(5)）微谐振器，其中光学参数振荡是在毫瓦级泵浦阈值功率下实现的，这为片上泵浦梳的产生铺平了道路。(C) 2016年美国光学学会
The combination of nonlinear and integrated photonics enables Kerr frequency comb generation in stable chip-based micro-resonators. Such a comb system will revolutionize applications, including multi-wavelength lasers, metrology, and spectroscopy. Aluminum gallium arsenide (AlGaAs) exhibits very high material nonlinearity and low nonlinear loss. However, difficulties in device processing and low device effective nonlinearity made Kerr frequency comb generation elusive. Here, we demonstrate AlGaAs-on-insulator as a nonlinear platform at telecom wavelengths with an ultra-high device nonlinearity. We show high-quality-factor (Q > 10(5)) micro-resonators where optical parametric oscillations are achieved with milliwatt-level pump threshold powers, which paves the way for on-chip pumped comb generation.
