An alternative solution to achieve a broadband gain in QD devices is to use multiple layers with different QD heights, which are stacked vertically, i.e. a chirped QD structure in the active region. In the chirped stacked QD structure, the vertical strain and electron coupling effect have a significant impact on the optical transition property and thus optical gain bandwidth. However, previous studies on the vertical coupling effect have mainly focused on uniformly stacked QD structures, and the chirped QD structures have not been investigated carefully. This work presents a detailed analysis of the vertical coupling effect in chirped QD structures (i.e. ascending and descending chirped structure) and its impact on the optical gain bandwidth of the active region. It is found that the descending chirped structure leads to a wider gain bandwidth, in particular at high current injection. A Fabry-Perot mode-locked laser with the descending chirped structure presents a better performance in pulse width and frequency comb lines compared to the ascending chirped structure.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 2","pages":"1-9"},"PeriodicalIF":2.5,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139744753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high-performance atomic clock system requires laser linewidths below 10 MHz to ensure compatibility with the natural atomic linewidth (e.g., 5 MHz for cesium). However, the current prevalent method for reducing VCSEL linewidths relies on external cavities, which adds complexity and cost to the devices and hampers seamless integration into atomic clock systems. While narrow-linewidth VCSELs have been successfully demonstrated using extended cavities, there remains a need for a comprehensive and systematic study on the underlying design principles and optimization strategies. Here, we propose a VCSEL linewidth narrowing strategy enabled by internal-cavity engineering for cesium atomic clock applications. We investigate strategies to narrow the cold cavity linewidth without introducing additional optical round-trip loss. We provide a general approach to constructing the extended cavity (EC) and showcase the ability of manipulating the phase of light. To optimize the electrical properties, we explore variations in the extended layer thickness based on a monolithic VCSEL structure. We proposed an EC-VCSEL configuration with a theoretical laser spectral linewidth of approximately 1.7 MHz and a calculated output power of about 3 mW. Through exploiting gain-cavity offset, the EC-VCSEL exhibits a stable emission (894.6 nm) and a high gain of cavity mode (\u0000<inline-formula> <tex-math>$sim $ </tex-math></inline-formula>\u00004000 cm\u0000<inline-formula> <tex-math>$^{-1}$ </tex-math></inline-formula>\u0000) at high-temperature (e.g., 360 K). This work may serve as a reference for the realization of narrow-linewidth VCSELs, offering potential benefits in reducing device complexity and facilitating the system integration.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 2","pages":"1-8"},"PeriodicalIF":2.5,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139946553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
