英文原题Three-Dimensional Coupled-Wave Analysis for Photonic-Crystal Surface-Emitting Lasers With External Optical Feedback

中文摘要光子晶体面发射激光器（PCSEL）通过引入光子晶体谐振器实现大面积相干振荡，从而获得高输出功率和优异的光束质量。光子晶体设计的进步带来了更强的功能，包括光束转向、高速调制和窄线宽运行。作为进一步扩展 PCSEL 功能的一种有前景的方法，本文考虑了由外部反射器引起的自注入光反馈；此前已有研究表明，该方法可在传统半导体激光器中实现线宽压窄和调制带宽扩展。本文开发了一种能够分析具有外部光反馈的 PCSEL 的数值方法，并基于该框架对其激光振荡特性开展理论研究。首先，我们表明激光振荡模……

英文摘要Photonic-crystal surface-emitting lasers (PCSELs) enable large-area coherent oscillation by incorporating a photonic crystal resonator, thereby realizing high output power and excel lent beam quality. Advances in photonic-crystal design have led to enhanced functionalities, including beam steering, high-speed modulation, and narrow-linewidth operation. As a promising approach to further extending the functionality of PCSELs, self-injection optical feedback induced by an external reflector, which has been previously reported in conventional semiconductor lasers to achieve linewidth narrowing and expansion of the modulation bandwidth, is considered. In this paper, we develop a numerical method that enables the analysis of PCSELs with external optical feedback, and we conduct a theoretical investigation on its lasing characteristics based on this framework. First, we show that the lasing mo

中文摘要我们从理论上设计了一种基于三角形孔和圆形孔的双晶格光子晶体面发射激光器（PCSEL）。在该设计中，首次提出采用多孔 GaN 作为 GaN-PCSEL 的包层；多孔 GaN 具有较低折射率，并可与 GaN 实现高质量、无应力的同质外延。研究采用了有限差分时域（FDTD）、平面波展开（PWE）和严格耦合波分析（RCWA）方法。我们的模拟在保持低阈值增益的同时，实现了高达 50 cm⁻¹ 的辐射常数和超过 1 W/A 的斜率效率。我们系统研究了填充因子、蚀刻深度和孔位移对 PCSEL 性能的影响。研究结果表明，增大填充因子可提高辐射常数和斜率效率。非对称孔图案……

英文摘要We have theoretically designed a double-lattice photonic crystal surface-emitting laser (PCSEL) based on triangular and circular holes. In the design, porous-GaN which has the properties of lower refractive index and high quality stress-free homo-epitaxy with GaN, was first proposed to be the cladding layer for GaN-PCSEL. The finite difference-time domain (FDTD), the plane wave expansion (PWE), and the rigorous coupled-wave analysis (RCWA) method were employed in the investigation. Our simulations achieved a radiation constant of up to 50 cm-1 and a slope efficiency of more than 1 W/A while maintaining a low threshold gain. We conducted a systematic study on the effects of the filling factor, etching depth, and holes shift, on the performance of the PCSEL. The findings indicate that increasing the filling factor improves the radiation constant and slope efficiency. Asymmetric hole patter

中文摘要我们报道了一种准光子晶体面发射激光器（QPCSEL），其采用被高折射率外延半导体包围的亚微米低折射率掩埋介质结构来形成准光子晶体层。我们展示了掩埋介质 QPCSEL 在室温下、发射波长为 1.5 μm 的光泵浦激光振荡。QPCSEL 用准周期光子晶体取代传统的周期性折射率图案，从而产生单模发射。我们的掩埋介质方案能够实现光子晶体的固态集成，同时在外延半导体再生长过程中保留复杂的图案化几何结构。

英文摘要We report a quasi-photonic-crystal surface-emitting laser (QPCSEL) that employs sub-micron, low-index buried dielectric features surrounded by high-index epitaxial semiconductor to form the quasi-photonic-crystal layer. We demonstrate photopumped lasing from a buried dielectric QPCSEL at room temperature with emission wavelength at 1.5 μm. QPCSELs replace the conventional periodic refractive index pattern with a quasi-periodic photonic crystal, which produces single mode emission. Our buried dielectric approach enables solid-state integration of the photonic crystal while preserving the complex patterned geometry during epitaxial semiconductor regrowth.

英文原题High-purity linearly polarized emission from a compact BIC laser

中文摘要连续域束缚态（BIC）赋予光子晶体（PhC）激光器超高品质因子，从而实现低阈值。然而，BIC 具有动量空间矢量偏振涡旋，这对实现高纯度偏振发射构成了重大障碍。传统上，可以通过各种对称性扰动来控制 PhC 激光器的偏振。然而，由于实际激光系统固有的有限尺寸效应，其发射的偏振纯度较低。因此，在不显著牺牲其他性能指标的情况下实现 PhC 激光发射的高偏振纯度，一直是一项持续存在的挑战。在此，我们开发了一种色散辅助偏振控制策略，用于对 PhC 激光发射进行单片式偏振工程。作为概念验证，我们展示了一种紧凑型准 BIC 的线偏振发射。

英文摘要Bound states in the continuum (BICs) confer ultrahigh quality factors and, thus, enable low thresholds upon photonic crystal (PhC) lasers. However, BICs feature a momentum-space vectorial polarization vortex, posing a substantial obstacle in achieving high-purity polarized emission. Traditionally, polarization control of a PhC laser can be achieved through various symmetry perturbations. However, the emission suffers from low polarization purity due to the finite-size effect inherent in real laser systems. Achieving a high polarization purity in PhC laser emission without significantly sacrificing other performance metrics has thus been a persistent challenge. Here, we develop a dispersion-assisted polarization control strategy for monolithic polarization engineering of PhC laser emission. As a proof of concept, we have demonstrated a linearly-polarized emission from a compact quasi-BIC

英文原题High-Power Terahertz Photonic Crystal Surface-Emitting Laser with High Beam Quality

中文摘要光子晶体面发射激光器（PCSEL）因具有较小的远场发散角和较高的输出功率而备受关注。在此，我们通过优化吸收边界条件并引入对称分布的电极，报道了一种具有高光束质量的高功率太赫兹（THz）光子晶体激光器。该器件实现了 3.4 THz 的单模表面发射，最大峰值输出功率为 50 mW。同时，还获得了具有 C6 对称性的高度对称远场图案和较小的发散角。该器件实现了稳定单模运行、高光束质量和高输出功率的集成，这对于实际应用可能具有重要意义。

英文摘要The photonic crystal surface-emitting laser (PCSEL) has attracted much attention due to the advantages of a small far-field divergence angle and high output power. Here, we report a high-power terahertz (THz) photonic crystal laser with high beam quality through the optimization of the absorption boundary condition and the introduction of the symmetrically distributed electrodes. Single-mode surface emission at 3.4 THz with the maximum peak output power of 50 mW is demonstrated. Meanwhile, a high symmetric far-field pattern with C6 symmetry and a small divergence angle is achieved. In this device, the integration of the stable single-mode operation, high beam quality and high output power is realized, which may have great significance for practical applications.

英文原题Regrowth-free blue GaN-based photonic crystal surface-emitting lasers with triangular air holes

中文摘要我们报道了采用免再生长方法成功实现的一种室温蓝色 GaN 光子晶体面发射激光器（PCSEL）二极管。通过采用具有改进型三角形空气孔的方形晶格光子晶体结构，我们实现了稳健的二维单模激光振荡。该器件的阈值电流密度为 5.2 kA/cm²，并发射高斯形光束，光束发散角极低，测得为 1.15 mrad（0.066°）。此外，三角形空气孔的对称性破缺特性可强制形成垂直于三角形长边的稳定线偏振。这项工作表明，采用具有简单孔形的免再生长制造工艺可以实现高光束质量的蓝色 PCSEL，为高性能蓝色激光光源铺平了道路。

英文摘要We report the successful realization of a room-temperature blue GaN photonic crystal surface-emitting laser (PCSEL) diode fabricated using a regrowth-free approach. By employing a square lattice photonic crystal structure with modified triangular air holes, we achieve robust two-dimensional single-mode lasing. The device operates with a threshold current density of 5.2 kA/cm2 and emits a Gaussian-shaped beam with exceptionally low beam divergence, measured at 1.15 mrad (0.066°). Furthermore, the symmetry-breaking nature of the triangular air holes enforces a stable linear polarization perpendicular to the long edge of the triangle. This work demonstrates that high-beam-quality blue PCSELs can be achieved using non-regrowth fabrication processes with simple hole geometry, paving the way for high-performance blue laser sources.

英文原题Inverse Design of Photonic Crystal Lasers Through Automatic Differentiation Optimization

中文摘要（嵌入式）PhC 谐振器激光器的行为与其晶胞轮廓密不可分。因此，遗憾的是，设计过程中的绝大部分工作依赖于对介电常数分布进行审慎的人工选择。这种做法的不利之处在于，它丢弃了与目标函数（激光器的物理响应）相关的信息。我们通过采用基于梯度的方案来解决这一问题，该方案将计算设计任务分为两个步骤，涉及用于光子本征模的二维本征值问题（建模）和计算图（梯度传播）：（i）对模拟执行前向传播，以预测光子晶体面发射激光器（PCSEL）的行为（远场和模式品质因子）；（ii）执行反向传播步骤，计算（用户）定义的代价函数的梯度，以更新晶胞设计。性能……

英文摘要The behavior of (embedded) PhC resonator lasers is inextricably linked to the unit cell profile. Hence, an overwhelming fraction of the design process unfortunately relies on the judicious manual choice of the permittivity profile. This is disadvantageous for the fact that this throws away information regarding the objective function (the physical response of the laser). We remedy this by employing gradient-based protocols that split the computational design task into two steps—between a 2D eigenvalue problem for the photonic eigenmodes (modeling) and the computational graph (gradient-propagation): (i) a forward passage through the simulation to predict the photonic-crystal surface-emitting laser (PCSEL) behavior (far-field and mode quality factors), and (ii) a backpropagation step where the gradient of a (user) defined cost function is computed to update the unit cell design.
