The development of a single modulation unit featuring simple structure and high modulation depth caters to the trend towards the miniaturization, integration, and multi-functionality of on-chip terahertz modulators. In this work, we propose a terahertz modulation unit in the form of a split-ring resonator integrated in series with microstrip lines for amplitude modulation. The modulator unit features an insertion loss of less than 1 dB under the On state, and a maximum modulation depth exceeding 30 dB under the Off state with an operational bandwidth greater than 15 GHz at 140 GHz. Subsequently, both the series-coupled and the dual-arm configuration of such a unit design for dual-band modulation were demonstrated. Series-coupled configuration featuring seamless connected units allows simultaneous modulation of terahertz carrier waves within multiple bands. Whilst dual-arm configuration consisting of a single split ring resonator unit having compact structure, but with challenges in multi-band modulation. Finally, we propose a characterization methodology of terahertz on-chip modulators involving a non-ideally conforming waveguide-finline-microstrip transition. Such conversion circumvents the challenges associated with conventional chip testing methods, and is highly practical in revealing the performance of stand-alone components. We believe that the proposed terahertz modulator unit design holds strong potential to provide compact and integrated solutions for analog signal processing in the upcoming Terahertz communications.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"579 ","pages":"Article 131546"},"PeriodicalIF":2.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143159004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The theoretical calculations and experimental results demonstrate that the established module achieves a measurement accuracy of ±10 nm in high-NA systems. Through the application of this module, the in-situ movement fluctuation error of the x-y motorized stage in the direct laser writing lithography system was measured.

Based on the results, the corrections were carried out to decrease the installation errors of the motorized stage, an optimized average movement error of ±0.554 μm is obtained, which is 84.1% lower than the initial value before optimization. For 50 mm × 50 mm movement area, the measurement results and direct laser lithography results confirmed that the fluctuation error after correction was within the acceptable range.

The interaction between a laser and fused silica is a complex phenomenon that typically involves interactions across multiple spatiotemporal scales and physical fields. In this paper, a coupled macro-micro multiscale simulation technique based on temperature field is proposed. This method permits the observation of the spatiotemporal multiscale evolution mechanism underlying the interaction between a nanosecond pulsed laser and fused silica. The temperature distributions at various locations at the laser energy, obtained from a heat conduction model, are employed as inputs for laser energy in microscopic molecular dynamics simulations. This approach is employed to elucidate the atomic structure changes induced by laser radiation in fused silica, thereby providing a rapid dynamic correspondence of the processes occurring in fused silica irradiated by nanosecond pulsed laser. The results of the macroscopic and microscopic simulations demonstrate that the damage mechanism in fused silica can be divided into three distinct regions: the solid, melting, and ablation regions. The damage behavior is primarily ascribed to the internal atomic phase transition mechanism. Additionally, the laser fluence has a pronounced impact on the structural alterations occurring within fused silica. It was observed that fused silica undergoes thermal melting at a laser fluence of 1.0 J/cm<sup>2</sup>, at 3.0 J/cm<sup>2</sup> the melting state coexists with ablation, and above 4.0 J/cm<sup>2</sup> a large amount of atomic ablation is observed.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"579 ","pages":"Article 131523"},"PeriodicalIF":2.2,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143159942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-Hermitian scattering properties of the 1D photonic structure with different spatially chirped defect layers are explained using the transfer matrix method (TMM) and scattering matrix. The proposed 1D photonic structure exhibits enhanced non-reciprocal reflection with constant loss and gain in the defect layer. In contrast, periodic modulations in loss and gain lead to unidirectional amplification of discrete defect mode. The considered 1D structure is also investigated with the variation in incident angle, which shows the shift of certain defect modes towards higher frequencies and the conversion of perfect absorption points to lasing points for forward and backward incidences. In addition, different chirped profiles of loss and gain modulate the defect modes significantly and induce amplification at a particular incident angle and loss/gain value. The observed amplifications of defect modes can enact unidirectional as well as bidirectional lasing action with proper choice of the chirp profile of gain and loss in the defect layer.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"579 ","pages":"Article 131521"},"PeriodicalIF":2.2,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143159010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
