英文原题Buried dielectric quasi-photonic-crystal surface-emitting lasers

中文摘要我们报道了一种准光子晶体面发射激光器（QPCSEL），其采用由高折射率外延半导体包围的亚微米级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 在室温下的光泵浦激射，其发射波长为 1.5 μm。QPCSEL 以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

中文摘要连续体束缚态（BIC）可为光子晶体（PhC）激光器带来超高品质因数，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，由于真实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 激光器发射的高偏振纯度，一直是一项挑战。在此，我们提出了一种色散辅助偏振控制策略，用于对 PhC 激光器发射进行单片式偏振调控。作为概念验证，我们展示了一种紧凑型准 BIC 激光器的线偏振发射，其偏振消光比高达约 300:1，同时保持了单模运行和高光束质量。我们的工作为片上激光器的高效偏振调控开辟了道路。所得器件可提供微型化偏振光源，适用于相干光通信、先进显示技术及多种精密测量。

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 laser with a high polarization extinction ratio of ~300:1, while single-mode operation and high beam quality are well-maintained. Our work paves a way for efficient polarization tailoring of on-chip lasers. The resulting devices deliver a miniaturized polarization light source for applications across coherent optical communication, advanced display technology, and diverse precision measurements.

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制造的室温蓝光 GaN 光子晶体面发射激光器（PCSEL）二极管的成功实现。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射。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确保了垂直于三角形长边的稳定线偏振。该工作表明，采用具有简单孔洞几何形状的免再生长制造工艺可以实现高光束质量的蓝光 PCSEL，为高性能蓝光激光源铺平了道路。

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 谐振腔激光器的行为与晶胞轮廓密不可分。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。这样做的缺点在于，它舍弃了与目标函数（激光器的物理响应）相关的信息。我们采用基于梯度的方法来解决这一问题，将计算设计任务分为二维光子本征模特征值问题（建模）和计算图（梯度传播）之间的两个步骤：（i）通过仿真进行前向传播，以预测光子晶体面发射激光器（PCSEL）的行为（远场和模式品质因数）；（ii）进行反向传播，计算用户定义的代价函数的梯度，以更新晶胞设计。在远场和腔内场性能指标方面，该方法的性能均优于当前用于大规模 PCSEL 的晶胞设计。

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. The performance of this method exceeds contemporary unit cell designs for large-scale PCSELs in both far-field and intracavity field performance metrics.

英文原题Graph State Generation Based on Quantum Photonic Devices, Enabling Measurement-Based Quantum Computing

中文摘要光子簇态是基于测量的量子计算（MBQC）的基础资源，而 MBQC 是一种很有前景的可扩展量子计算方法。这些高度纠缠态能够通过局域测量而非门操作实现计算，因此对于容错量子计算至关重要。光子簇态的生成需要高质量的纠缠和稳定性，这可以通过腔量子电动力学（cavity QED）来实现，即将量子点（QD）嵌入光子微腔中。该方法能够实现受控的单光子发射及其纠缠，有助于解决光子簇态生成中的关键挑战。增强光子簇态的生成需要提高腔与 QD 系统的品质因数（Q factor），进而提升其协同性。高 Q factor 有助于减少光子损耗和退相干，从而确保量子态更加稳定并具有更高保真度。它还能增强光与物质的相互作用，提高簇态质量。协同性用于衡量光–物质耦合强度相对于耗散的大小，并直接影响光子发射效率。对这些参数进行优化可改善纠缠生成，而这对于产生高质量光子簇态至关重要。因此，优化腔体对于改善光子簇态的生成至关重要。可扩展性也是生成量子计算所用大规模簇态的一个重要参数。本文在综述 MBQC、簇态及光子簇态生成之后，研究了用于 MBQC 的光子簇态资源的确定性生成，并强调了逆向设计技术对于实现这一目标的重要性。

英文摘要Photonic cluster states are fundamental resource for measurement-based quantum computing (MBQC), which is a promising approach for scalable quantum computing. These highly entangled states enable computation with applying local measurements rather than gate operations, which makes them essential for fault-tolerant quantum computing. Generation of the photonic cluster states requires high-quality entanglement and stability, which can be done by making use of cavity quantum electrodynamics (cavity QED), which is embedding quantum dots (QDs) into photonic microcavities. This method enables controlled single-photon emission and the entanglement of them, helping with key challenges in generating photonic cluster states. Enhancing the generation of the photonic cluster state requires improvement in the quality factor (Q-factor) and therefore, cooperativity of cavity and QD systems. A high Q-factor helps with reduction in photon loss and decoherence, ensuring more stable and high-fidelity quantum states. It also enables better light-matter interactions, improving cluster state quality. Cooperativity, which is a measure for the light-matter coupling strength relative to dissipation, directly impacts photon emission efficiency. Optimization of these parameters improves entanglement generation, which is essential for producing high-quality photonic cluster states. Therefore, optimized cavities are essential for improving the generation of the photonic cluster states. Scalability is also an important parameter for the generation of the large-scale cluster states used in quantum computing. In this paper, after reviewing MBQC, cluster states, and the generation of the photonic cluster states, we investigate the deterministic generation of the photonic cluster state resource for the purpose of MBQC, and highlights the importance of the inverse design techniques for this goal.
