In our work, the graphene monolayer provides the enabling nonlinearity, by means of its third-order surface conductivity. We use the Lugiato-Lefever equation framework, modified to incorporate the frequency dispersion of all eigenmode properties—including nonlinearity—in an ultrawide octave-spanning spectrum. The waveguide parameters are rigorously computed by a full-vector mode solver where we input graphene’s full set of electromagnetic properties, both linear and nonlinear; the latter are extracted by quantum perturbation formulas, as a function of graphene’s chemical potential and equilibrium lattice temperature. Our results show the potential of graphene, as a 2D material with electrically tunable linear and nonlinear response, for Kerr combs or other integrated nonlinear devices, such as mode-locked and Q-switched lasers.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 2","pages":"1-9"},"PeriodicalIF":2.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10904487","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the increasing application demand, in comparison to the one with ultrashort pulse duration and broad spectral bandwidth, there is less attention given to the generation of narrowband spectra in mode-locked lasers. In this contribution, we demonstrate a passively mode-locked ytterbium-doped fiber laser that relies on a standard fiber Bragg grating (FBG) as a narrowband reflector and a nonlinear amplifier loop mirror (NALM) as a saturable absorber. This laser can generate stable pulses with a pulse duration of 124.3 ps and an ultranarrow 3 dB spectral bandwidth of 27 pm. Both numerical simulations and experiments have demonstrated that adjusting the fiber length bias within the NALM loop to suppress nonlinear-induced spectral broadening can effectively facilitate the generation of narrowband mode-locked pulses.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 2","pages":"1-5"},"PeriodicalIF":2.2,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716428","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 practical design of the cascade laser, which is pumped by a 751 nm fiber laser, is determined by modeling it using an eight-level rate equation system that involves experimental spectroscopic parameters. By utilizing a 1.3-m-long Ho3+: ZrF4 fiber with a dopant concentration of 0.1 mol.% and assuming a pump power of 10 W launched into the fiber’s core, the simulation results show that this cascade system can achieve a slope efficiency of 38.9% and a maximum output power of 2.94 W. The result obtained prompts the development of a 1662 nm fiber laser that is based on a commercially available ZrF4 fiber. This laser has potential for a variety of applications, including telecommunications, gas sensing, multiphoton fluorescence microscopy, and pump sources.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 2","pages":"1-8"},"PeriodicalIF":2.2,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716536","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}
