The investigation of a fiber laser utilizing ytterbium-doped hybrid passively mode-locking, featuring a novel copper oxide-doped zinc oxide saturable absorber (CuO-ZnO SA), has been realized. The hybrid mode-locked (hybrid-ML) fiber laser integrates the nonlinear polarization rotation (NPR) technology with the CuO-ZnO-SA, producing remarkable characteristics with a central wavelength of 1045 nm, a 3-dB bandwidth spanning 18.26 nm, an ultra-short pulse width of 98 fs, a repetition frequency of 1.96 MHz, and an impressive signal-to-noise ratio of 51 dB. This research demonstrates a substantial enhancement in laser performance compared to NPR mode-locking alone. Notably, the pulse width experiences a significant compression, reduced by 39 fs, while the signal-to-noise ratio sees a noteworthy improvement of 11 dB. Furthermore, when contrasted with passively mode-locked pulse lasers relying solely on NPR technology, the hybrid passively mode-locked fiber laser attains a substantial reduction in output pulse width, surpassing 98 fs. These findings show the significant potential of the hybrid-ML system in the realm of ultrafast lasers, offering a promising avenue for future applications in cutting-edge research and technology.
研究人员利用新型氧化铜掺氧化锌可饱和吸收体(CuO-ZnO SA)实现了掺镱混合被动锁模光纤激光器。这种混合锁模(hybrid-ML)光纤激光器集成了非线性偏振旋转(NPR)技术和氧化铜-氧化锌可饱和吸收体(CuO-ZnO-SA),具有中心波长 1045 nm、3 dB 带宽 18.26 nm、超短脉冲宽度 98 fs、重复频率 1.96 MHz 和令人印象深刻的 51 dB 信噪比等显著特点。这项研究表明,与单独的 NPR 模式锁定相比,激光器的性能有了大幅提升。值得注意的是,脉冲宽度大幅压缩,减少了 39 fs,而信噪比则显著提高了 11 dB。此外,与完全依赖 NPR 技术的被动模式锁定脉冲激光器相比,混合被动模式锁定光纤激光器的输出脉冲宽度大幅缩短,超过了 98 fs。这些研究结果表明,混合 ML 系统在超快激光领域具有巨大潜力,为未来在尖端研究和技术领域的应用提供了广阔前景。

We propose an energy transfer model with a cubic atomic population dependence to accurately model the behavior of various reported high-power erbium-doped fluoride fiber lasers operating near 2.8 microns. We first show that the previously introduced weakly interacting (WI) and strongly interacting (SI) models are not adequate for precisely modeling such high-power erbium-doped fluoride fiber lasers. We compare results obtained with the WI and SI models to the proposed model by simulating 4 different highly doped (7 mol.%) fiber lasers previously reported in the literature. Laser efficiencies and powers are reproduced with great accuracy. In addition, four other fiber laser systems based on erbium concentrations varying from 1–6 mol.% are also simulated with good accuracy using the proposed model with the exact same set of spectroscopic parameters, which confirms its validity for various erbium doping concentrations. Redshifting of laser wavelength is also taken into account by considering the full cross section spectra and computing signal powers over several wavelength channels.
我们提出了一种具有立方原子群依赖性的能量传递模型,以精确模拟各种已报道的在 2.8 微米附近工作的高功率掺铒氟化物光纤激光器的行为。我们首先表明,之前引入的弱相互作用(WI)和强相互作用(SI)模型不足以精确模拟此类大功率掺铒氟化物光纤激光器。我们通过模拟先前在文献中报道的 4 种不同的高掺杂(7 mol.%)光纤激光器,将 WI 和 SI 模型获得的结果与所提出的模型进行了比较。激光效率和功率都得到了非常精确的再现。此外,使用所提出的模型和完全相同的光谱参数集,还精确地模拟了铒浓度为 1-6 摩尔%的其他四种光纤激光器系统,这证实了该模型对各种铒掺杂浓度的有效性。通过考虑全截面光谱和计算多个波长通道的信号功率,还考虑了激光波长的红移。

A tapered fiber plasmon sensor with a tip angle of about 30 degrees was fabricated to realize optical absorption and application to an optical sensor using localized plasmon in the 1500 nm wavelength band. The sharp tip angle of a single-mode fiber (SMF) was well controlled by using a highly GeO2-doped single-mode fiber (SMF) and optimizing the etching conditions with buffered fluoric acid. Gold nanoparticles (Au-NPs) with a diameter of 40 nm were deposited by treating the surface of a tipped SMF with silane coupling. The relationship between Au NPs deposition time and deposition ratio was studied to control Au NPs distribution and pursue higher sensitivities. The wavelength sensitivity of 662 nm/RIU was expected at Au NPs deposition ratio of 34.9 % in the analysis, and actually a high sensitivity of 677 nm/RIU at 35.3 % was experimentally demonstrated.

A high-speed and high-power modified uni-traveling-carrier photodiode (MUTC-PD) is optimized and fabricated. The optimization method takes carrier transport as the core and considers the hole transport time limited bandwidth of the MUTC-PD for the first time. Taking into account the impact of the electron transport time and RC time constant on device performance, the device is simulated and fabricated. In structure epitaxy, it is proposed to use graded doping to fit Gaussian doping to reduce the epitaxial growth error. The measured bandwidth of the MUTC-PD reaches 34 GHz and the RF output power reaches 17.1 dBm with the mesa diameter of $20~mu text{m}$
