论文摘要
频率梳已成为光学研究领域的重要研究领域。特别有趣的作为集成梳技术的是芯片尺度来源,例如半导体激光器和微孔子,它们由嵌入具有或没有种群反转的非线性培养基的谐振器组成。如此活跃和被动的空腔已被明确处理。在这里,我们通过引入描述两种腔的通用方程来提出正式统一。该方程式还捕获了混合装置的物理学 - 具有外部光学驱动器的半导体环激光器 - 我们显示了颞孤子的存在,此前仅在微孔子中仅在微孔子中鉴定,这要归功于对称性破坏和自我定位现象,典型的空间扩展了散发出耗散系统。
Frequency combs have become a prominent research area in optics. Of particular interest as integrated comb technology are chip-scale sources, such as semiconductor lasers and microresonators, which consist of resonators embedding a nonlinear medium either with or without population inversion. Such active and passive cavities were so far treated distinctly. Here we propose a formal unification by introducing a general equation that describes both types of cavities. The equation also captures the physics of a hybrid device - a semiconductor ring laser with an external optical drive - in which we show the existence of temporal solitons, previously identified only in microresonators, thanks to symmetry breaking and self-localization phenomena typical of spatially-extended dissipative systems.
