The stable passively mode-locked laser based on Au TA is obtained with a repetition rate of 2.08 MHz and a pulse period of 480 ns for a pump power of 704 mW at 1558 nm.

The thin-core fiber is sputtered with gold film to excite SPR, and then the probe is coated with enzyme coating that is formed by embedding urease in zeolitic imidazolate framework (ZIF -8/Urease) to realize a highly specific urea biosensor. The bind of urea and urease in the zeolitic imidazolate framework will cause the change of refractive index of the SPR probe, which will then induce the wavelength shift of SPR resonance spectrum. Experimental results demonstrated that the resonance wavelength has a good linear relationship with the urea concentration in the range of 1–10 mM, and the sensitivity can reach to 4 nm/mM.","PeriodicalId":6756,"journal":{"name":"2021 19th International Conference on Optical Communications and Networks (ICOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81683819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The four sensors are based on extrinsic Fabry-Perot interferometry (EFPI), which are constructed by splicing a section of hollow-core fiber (HCF) of about 500µm between two single-mode fiber (SMF) segments. Each sensor corresponds to one demodulation channel. We use a vernier-turned distributed Bragg reflector (VT-DBR) laser for high-speed wavelength switching, which introduces a phase shift in the wavelength domain. Based on five-step phase-shifting algorithm, phase recovery is performed with any five adjacent phase-shifting signal to achieve high-speed and stable phase demodulation. Experimental results show that this measurement system can be well applied to high-speed measurement of strain.","PeriodicalId":6756,"journal":{"name":"2021 19th International Conference on Optical Communications and Networks (ICOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72588368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
