This strain sensor is fabricated through mechanical polishing and arc-discharging, allowing for certain control over its sensitivity to strain. The single-mode fiber (SMF) is first preprocessed into a D-shaped fiber (DSF) through polishing. Then, a periodic melting-induced shrinking is applied to the fiber through arc-discharging modulation. The polishing and shrinking enhance the asymmetry of the single-mode fiber. The discharge modulation enables convenient control of the mode order coupling efficiency and the shrinking level of the sensor, thereby effectively controlling and improving the strain sensitivity. The experimental results indicate that strain sensors with three levels of sensitivity, namely high, medium, and low sensitivity, are obtained by controlling the number of discharges.

However, most structured microwave generation arrays can only produce a single type of beam. This study proposes a three-functional multiplexing metasurface based on the principles of circular polarization decoupling and Pancharatnam-Berry (PB) phase. At 10.5 GHz, when illuminated by different circular polarized (CP) waves, this metasurface generates output waves that can separate OAM beams, spiral beams, and self-focusing Airy beams based on their polarization states. This metasurface holds broad applications in high-performance near-field wireless communications.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141717623","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}

Still the thermal cross-talk deriving from the integration of multiple sub-THz signals may be detrimental on the long-term scale, strongly affecting the working frequencies of the circuit. In this letter, a flexible generation of a beat note at a multiple of 50 GHz and its stabilisation in the frequency domain through an integrated silicon nitride high Q resonator-based locker are reported. As a field-test, two generated beat note signals at 100 and 150 GHz, respectively, were launched into a 183.8 km long dark fibre network. To evaluate the frequency locker system robustness, an external frequency drift of -125 MHz/hour that mimicked a thermal drift (~2°C/hour) was applied to one laser. The integrated apparatus allows the stabilisation of the generated frequency tone, with a maximum variation of \u0000<inline-formula> <tex-math>$pm ~30$ </tex-math></inline-formula>\u0000 MHz around the nominal value. In principle, the adopted free-dispersion design of the SiN waveguide makes possible to place two spectral lines far enough to generate thermally stable THz-waves.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141717625","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}
