In this study, <inline-formula> <tex-math>$340mu $ </tex-math></inline-formula>m thick BIG films are randomly positioned within the resonant cavity of a Nd:YVO<inline-formula> <tex-math>${}_{mathbf {4}}$ </tex-math></inline-formula> laser at 1342 nm. The saturation magnetic field required for the BIG is only 80 mT. In the absence of an external magnetic field, no laser output is observed. However, when a saturated magnetic field is applied, the laser generates output instantaneously, achieving an output power of up to 485 mW under a pump power of 2987 mW. The experimental results demonstrate that the presence or absence of the output laser can be effectively controlled by adjusting the state of the magnetic field, thereby achieving magneto-optical modulation of the laser. This research not only expands the functional capabilities of BIG thick films, but also provides a novel and efficient intracavity modulation scheme for all-solid-state laser systems. This advancement is anticipated to have significant implications in laser communication, precision processing, quantum optics and other fields.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 23","pages":"1385-1388"},"PeriodicalIF":2.5,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036980","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}

By employing CPLUTs, the proposed CPLUT-VDFE not only eliminates all multiplication operations required for the implementation of the VDFE, but also significantly reduces the overall table size. The performance of the proposed CPLUT-VDFE is evaluated after Volterra feed-forward equalization in a C-band 112-Gb/s PAM-4 50-km transmission system. Experimental results demonstrate that the proposed CPLUT-VDFE, with 82 cluster centers, achieves comparable equalization performance to the cluster-assisting LUT-VDFE (CLUT-VDFE) with 110 cluster centers, while reducing the total table size by 71.1% and the number of real-valued additions by 25.7%. Furthermore, the proposed CPLUT-VDFE, with 42 cluster centers, can achieve a 99.9% reduction in total table size and a 62.4% decrease in the number of real-valued additions compared to the CLUT-VDFE with 110 cluster centers, at the expense of a 1-dB power penalty.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 24","pages":"1401-1404"},"PeriodicalIF":2.5,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036798","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}
