High-<i>Q</i> lithium niobate (LN) optical micro-resonators are excellent platform for future applications in optical communications, nonlinear optics and quantum optics. To date, high <i>Q</i> factors are typically achieved in LN using either dielectric masks or femtosecond laser ablation, while the more standard and commonly available lift-off metallic masks are often believed to lead to rough sidewalls and lowered <i>Q</i> factors. Here we show that LN microring resonators with strong light confinement and intrinsic <i>Q</i> factors over 1 million can be fabricated using optimized lift-off metallic masks and dry etching processes, corresponding to a waveguide propagation loss of ~ 0.3 dB/cm. The entire process is fully compatible with wafer-scale production and could be transferred to other photonic materials.

Special Issue on Lithium Niobate Based Photonic Devices

We demonstrate high-quality (intrinsic Q factor ～2.8 × 106) racetrack microresonators fabricated on lithium niobate thin film with a free spectral range (FSR) of ～86 pm. By integrating microelectrodes alongside the two straight arms of the racetrack resonator, the resonance wavelength around 1550 nm can be red shifted by 92 pm when the electric voltage is raised from -100 V to 100 V. The microresonators with the tuning range spanning over a full FSR are fabricated using photolithography assisted chemo-mechanical etching.

Sagnac干涉仪在光学滤波领域有着重要应用。基于三维氮化硅波导平台,利用双层的多微环系统实现了新型类Sagnac谐振滤波系统,其中底层主微环腔分别与顶层输入/输出波导和单/双子微环实现了反馈耦合。光经耦合区域产生了两束相向传输并互相干涉的光波,从而实现了滤波波形和谐振峰位可调的滤波结构。基于传输矩阵和迭代方法分析输出光谱,通过改变波导与微腔的耦合系数设计输出光谱波形,利用金属加热电极调制主微腔的相位以调控谐振峰位。理论分析和实验表征结果表明,通过增加顶层子微环数可有效增强器件的密集滤波效果,此三维集成结构可提供更多的设计自由度。相关的多微环谐振滤波系统可以广泛应用于光通信和光传感等领域。

Infrared and Terahertz Photonics

This Letter proposes a novel method for enhancing terahertz (THz) radiation from microstructure photoconductive antennas (MSPCA). We present two types of MSPCA, which contain split-ring resonators (SRRs) and dipole photoconductive antennas (D-PCAs). The experimental results reveal that when the femtosecond laser is pumping onto the split position of the SRR, the maximum THz radiation power is enhanced by 92 times compared to pumping at the electrode edge of the D-PCA. Two $π$ phase shifts occur as the pumping laser propagates from the negative electrode to the positive electrode. Analysis shows that photoinduced carrier charges move within the split position of the SRR.
