The mode-locking was achieved by using bismuth telluride (Bi2Te3) as an optical modulator in a praseodymium-doped fluoride fiber (PDFF) laser which operates at 1300.5 nm. Bi2Te3 was prepared by liquid phase exfoliation (LPE) process and then it was drop-casted onto the arc-shaped fiber, which behaves as an optical modulator. The mode-locking was obtained within the pump power range of 106.8 to 133.2 mW. The pulse repetition rate was at 0.407 MHz with a signal-to-noise ratio (SNR) of 53.4 dB. The ultrafast pulses of 890 fs duration with a pulse energy of 2.4 nJ were achieved. At the output, by using the offset splice spot (OSS) technique the higher-order modes were excited in the two-mode fiber (TMF). These higher-order modes were LP11 modes with a two-lobe structure visualized using the Thorlabs beam profiler.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 2","pages":"1-9"},"PeriodicalIF":2.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896409","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}

This made it possible to use the well-known photon transport equation for modeling the evolution of not only spatial and energy, but also spectral characteristics of radiation in high-power laser systems. This approach allows us to solve the problem of “negative probability” arising when using the Wigner distribution function for non-Gaussian laser beams. Comparison of the obtained data with the results of experiments and numerical modeling of amplification of chirped laser beams in the XeF(C-A) gas amplifier of the THL-100 laser system proved applicability of the model.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 2","pages":"1-5"},"PeriodicalIF":2.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888399","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}

Two definitions of an uncoupled waveguide system are introduced: the first involves connecting one of the two silicon waveguides to a boundary, directing its eigenmodes to the boundary, while the second removes one of the waveguides, resulting in eigenmodes confined to the remaining waveguide. The efficient design of adiabatic couplers is achieved by correcting and fitting the refractive indices of the even and odd eigenmodes in these uncoupled systems. The length of the adiabatic coupler designed by the proposed optimization method can be substantially reduced compared to the conventional linear adiabatic coupler. Calculations for the operating bandwidth of the designed adiabatic coupler show that the proposed optimization method can indeed achieve a paramount wide range of operating bandwidths (power transmission efficiencies of more than 90% are achieved for wavelengths from 1406 nm to 3775 nm). A comparison with other design methods demonstrates that the proposed optimization approach yields a coupler with higher efficiency than previous methods. These findings highlight the potential of this optimization strategy for designing high-performance adiabatic couplers with complex geometries in integrated optics.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 2","pages":"1-9"},"PeriodicalIF":2.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856244","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}
