英文摘要1674-1056/27/11/114211 Abstract By combing artificial micro–nano structures, photonic crystals (PCs), with traditional semiconductor laser material to realize the dynamic collaborative control of photonic states and confined electrons, the band engineering of the PC has been confirmed. This brings new development space for the semiconductor laser, such as for low threshold and high efficiency. Based on a series of works by Zheng’s group, this paper has reviewed kinds of PC lasers including electrical injection PC vertical cavity and lateral cavity surface-emitting lasers, and PC high beam quality lasers, to show that the PC is vital for promoting the continuous improvement of semiconductor laser performance at present and in the future.

英文原题Modulation of Coherently Coupled Phased Photonic Crystal Vertical Cavity Laser Arrays

中文摘要本文报道了发射波长为850 nm的双单元光子晶体离子注入相干耦合垂直腔面发射激光器阵列的调制特性。在同相或反相超模下均获得了单模发射，并在两种运行条件下均实现了显著的调制带宽增强。我们将该器件建模为一种单片集成、相互光注入锁定的激光器系统，并表明阵列单元之间的相位失谐和注入比是影响调制带宽的关键参数。实验测量结果与模型的比较与相互注入锁定机制相符。多个阵列设计均稳定实现了超过30 GHz、最高达37 GHz的调制带宽。我们表明，可以针对不同应用定制调制响应。

英文摘要The modulation properties of two-element photonic crystal ion-implanted coherently coupled vertical cavity surface emitting laser arrays emitting at 850 nm are reported. Single mode emission into either the in-phase or out-of-phase supermode and significant modulation bandwidth enhancement are obtained for both operating conditions. We model our device as a monolithically integrated, mutually optically injection-locked laser system and show that the phase detuning and injection ratio between array elements are critical parameters influencing modulation bandwidth. Comparison of our experimental measurements to our model is consistent with mutual injection locking. Modulation bandwidth greater than 30 GHz and up to 37 GHz is consistently found for several array designs. We show the modulation response can be tailored for different applications.

英文原题High-brightness scalable continuous-wave single-mode photonic-crystal laser

中文摘要摘要：实现能够媲美（甚至取代）笨重气体激光器和固体激光器的大规模、单模、高功率、高光束质量半导体激光器，是光子学和激光物理学的终极目标之一。然而，由于多模振荡的出现，传统高功率半导体激光器不可避免地遭受光束质量不佳的问题，而且在连续波（CW）运行下，破坏性的热效应还会使振荡失稳。在此，我们通过开发大规模光子晶体面发射激光器克服了这些挑战：在光子晶体内部对厄米耦合和非厄米耦合进行控制，并预先设置晶格常数的空间分布，使这些耦合即使在CW条件下也能得以维持。对于谐振直径达3 mm（对应材料中超过10,000个波长）的大尺寸光子晶体面发射激光器，我们实现了超过50 W的CW输出功率、纯单模振荡以及仅0.05°的极窄光束发散角。亮度这一同时涵盖输出功率与光束质量的品质因数达到了1 GW cm⁻² sr⁻¹，可与现有笨重激光器相媲美。我们的工作是迈向单模千瓦级半导体激光器的重要里程碑，预计此类激光器将在不久的将来取代传统且更为笨重的激光器。

英文摘要Abstract Realizing large-scale single-mode, high-power, high-beam-quality semiconductor lasers, which rival (or even replace) bulky gas and solid-state lasers, is one of the ultimate goals of photonics and laser physics. Conventional high-power semiconductor lasers, however, inevitably suffer from poor beam quality owing to the onset of many-mode oscillation 1,2 , and, moreover, the oscillation is destabilized by disruptive thermal effects under continuous-wave (CW) operation 3,4 . Here, we surmount these challenges by developing large-scale photonic-crystal surface-emitting lasers with controlled Hermitian and non-Hermitian couplings inside the photonic crystal and a pre-installed spatial distribution of the lattice constant, which maintains these couplings even under CW conditions. A CW output power exceeding 50 W with purely single-mode oscillation and an exceptionally narrow beam divergence of 0.05° has been achieved for photonic-crystal surface-emitting lasers with a large resonant diameter of 3 mm, corresponding to over 10,000 wavelengths in the material. The brightness, a figure of merit encapsulating both output power and beam quality, reaches 1 GW cm −2 sr −1 , which rivals those of existing bulky lasers. Our work is an important milestone toward the advent of single-mode 1-kW-class semiconductor lasers, which are expected to replace conventional, bulkier lasers in the near future.

英文原题Laterally coupled photonic crystal surface emitting laser arrays

中文摘要我们提出并研究了一种基于横向耦合光子晶体面发射激光器（PCSEL）的新型相干激光器阵列设计。作为一种新型半导体激光技术，PCSEL在平面腔内具有场约束，并沿表面法线方向发射激光束。通过采用异质结构光子晶体设计来调控PCSEL之间的横向耦合，我们能够实现PCSEL阵列的相干运行。本文展示了一种无源耦合PCSEL阵列设计的相干运行。我们在目标波长为1040 nm的GaAs基量子阱异质结构上制备了PCSEL阵列器件。实验结果表明，2×2 PCSEL阵列的光谱线宽为0.14–0.22 nm。通过自干涉实验表征了光束合成性能。观察到PCSEL阵列与单个PCSEL器件具有相近的相干性。我们采用无源横向耦合的紧凑型PCSEL阵列设计在片上光子计算、量子和信息处理领域具有潜在应用。

英文摘要We propose and investigate a novel coherent laser array design based on laterally coupled photonic crystal surface-emitting lasers (PCSELs). As a new type of semiconductor laser technology, PCSELs have field confinement in a planar cavity and laser beam emission in the surface normal direction. By engineering lateral couplings between PCSELs with heterostructure photonic crystal designs, we can achieve coherent operations from an array of PCSELs. In this paper, we demonstrate coherent operation from a passively coupled PCSEL array design. We fabricated PCSEL array devices on a GaAs-based quantum well heterostructure at a target wavelength of 1040 nm. Experimental results show that the 2-by-2 PCSEL arrays have spectral linewidth of 0.14–0.22 nm. Beam combining performance was characterized by self-interference experiments. Similar coherency between the PCSEL array and single PCSEL device was observed. Our compact PCSEL array designs by passive lateral coupling have potential applications in fields of on-chip photonic computing, quantum, and information processing.

英文摘要Propagation constants and amplitudes of eigenwaves of photonic crystal fibers are calculated numerically using an algorithm based on combination of the exact nonlocal boundary conditions method and the finite-element method. The design of fibers has a central large core filled with nematic liquid crystal. We investigate the influence of radii of the cladding air holes and their number as well as radius of the central liquid crystal on the spectral characteristics of fibers. Our results strongly suggest that radius of the crystal in contrast to the size and the number of capillaries has a significant influence on eigenwaves and propagation constants. Varying this radius we control the number of solutions of the problem for a fixed wavelength.
