The development of compact and energy-efficient miniaturised lasers is a critical challenge in integrated non-linear photonics. Current research focuses on the integration of subwavelength all-dielectric lasers in CMOS compatible platforms. These systems provide a viable alternative to state-of-the-art nanoplasmonic sources, whose practicality is often hindered by high metal losses. The efficiency of dielectric nanolasers, however, is affected by the diffraction limit of light, which restricts the degree of localisation achievable with standard resonator modes. The recent development of new types of radiationless states has brought a sharp innovation in the field of subwavelength dielectric lasers. Radiationless states are exotic electromagnetic solutions that originate from the complex superposition and interaction of several resonator modes. They are associated with a high degree of near-field localisation which makes them particularly advantageous for non-linear photonics applications. In this work, we provide an overview of the most recent theoretical and experimental efforts toward the development of integrated lasers and ultrafast sources based on the amplification of exotic radiationless states. In particular, we focus our attention on two specific types of radiationless states: optical anapoles and Bound States in the Continuum (BIC). By discussing their differences and similarities, we provide a unifying view of these distinct research areas and outline possible future directions for these innovative platforms.

通过无辐射状态的复杂工程集成纳米激光

紧凑型和节能型微型激光器的发展是集成非线性光子学中的关键挑战。当前的研究集中在亚波长全介电激光器在CMOS兼容平台中的集成。这些系统为最先进的纳米等离子源提供了可行的替代方法,后者的实用性通常会因高金属损耗而受到阻碍。然而,电介质纳米激光器的效率受光的衍射极限的影响,这限制了标准谐振器模式可实现的定位程度。新型无辐射态的最新发展带来了亚波长介电激光器领域的一项重大创新。无辐射状态是一种奇异的电磁解决方案,其源于几个谐振器模式的复杂叠加和相互作用。它们与高度的近场定位有关,这使得它们对于非线性光子学应用特别有利。在这项工作中,我们概述了基于奇异无辐射态的放大而发展集成激光器和超快光源的最新理论和实验成果。特别是,我们将注意力集中在两种特定类型的无辐射状态上:光学偶极子和连续体中的束缚态(BIC)。通过讨论它们的异同,我们提供了这些独特研究领域的统一观点,并概述了这些创新平台的未来可能发展方向。我们概述了基于奇异无辐射态放大的集成激光器和超快光源开发的最新理论和实验成果。特别是,我们将注意力集中在两种特定类型的无辐射状态上:光学偶极子和连续体中的束缚态(BIC)。通过讨论它们的异同,我们提供了这些独特研究领域的统一观点,并概述了这些创新平台的未来可能发展方向。我们概述了基于奇异无辐射态放大的集成激光器和超快光源开发的最新理论和实验成果。特别是,我们将注意力集中在两种特定类型的无辐射状态上:光学偶极子和连续体中的束缚态(BIC)。通过讨论它们的异同,我们提供了这些独特研究领域的统一观点,并概述了这些创新平台的未来可能发展方向。连续体中的光学偶极子和束缚态(BIC)。通过讨论它们的异同,我们提供了这些独特研究领域的统一观点,并概述了这些创新平台的未来可能发展方向。连续体中的光学偶极子和束缚态(BIC)。通过讨论它们的异同,我们提供了这些独特研究领域的统一观点,并概述了这些创新平台的未来可能发展方向。
