The impact of doped fiber characteristics, input signal power and input pumping power on the gain and the noise figure of the proposed amplifiers are comprehensively considered and compared. At an input pumping power of 350 mW and optimum praseodymium-doped fiber (PDF) length, the obtained results show that dual-pass model recorded higher gain than the single-pass scheme. This occurs because of the dual propagation of the forwarded and amplified spontaneous emission (ASE) signal through the gain medium. Moreover, both proposed configurations exposed better amplification performance at an input signal power of −10 dB compared to the higher input signal power of 0 dB. The dual-pass regime shows higher amplification gain than the single-pass one of about 4 dB and a maximum power conversion efficiency (PCE) of 14%. Indeed, the PDF core radius and doping concentration are considered as vital factors. Decrement of doped-core radius leads to a notable gain increment and NF decay, whereas low doping concentrations show very small signal gain compared to the optimized value.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76209374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 DSC algorithm introduces neural network prediction and improves the polling mechanism between Optical Network Unit (ONU) and Optical Line Terminal (OLT). DSC can be applied to multi-service VPON scenarios. By introducing neural network, the problem that traditional prediction methods can only predict one polling cycle service traffic will be solved. By establishing the separation mechanism of report cycle and prediction cycle, the idle time in multi-wavelength VPON is eliminated, and the bandwidth consumption caused by a large number of REPORT messages is reduced. By proposing differentiated service cycle polling mechanism, the transmission delay of high priority service traffic caused by the simultaneous interpreting of multiple services in offline DBA algorithm can be reduced. Finally, by the simulation and analysis, the effectiveness of the proposed model is demonstrated.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84108612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In our scheme, the single-sideband (SSB) modulated signals via PDM-DPMZM are divided into two branches, and so two ac power-phase mapping functions with higher slopes are formed by different polarization processing. Since one ac power-phase curve serves as a calibration line, the system can realize unambiguous AOA measurement with the phase range of −180°~180°. The value and direction of DFS can only be determined using an electrical spectrum analyzer (ESA). In addition, the scheme has a larger operating bandwidth because no filter is required. Simulation results show that the AOA from −83.92° to 83.92° is measured with an error of ±0.9°, and the DFS measurement within ±100 KHz is realized with an error less than ±5 × 10−3 Hz. The characteristics of low error, high precision, and wide bandwidth are important for microwave signal detection.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82851560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 optical tapering technology is used to taper the PMF. Then, the MMZI is attached to a wood pulp diaphragm (WPD) to form an acoustic sensor, whose curvature will change with the vibration of the diaphragm. Two sensors with different waist diameters are made for performance comparison. Experimental results show that the acoustic sensor can achieve a wideband frequency response range from 200 Hz to 4000 Hz. The responses are flat at frequencies ranging from 200 Hz to 1500 Hz. Moreover, we find that the sensing performance of the acoustic sensor improves with the decrease in its waist diameter. When the waist diameter is 25.72 μm, the response sensitivity of the sensor can reach 42.4 mV/kPa at 2000 Hz, and the minimum detection pressure is 1.24 Pa/√Hz. It provides an effective way to fabricate an acoustic sensor, with low cost, easy integration, and high sensitivity.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78792728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

However, fabrication and integration of graphene saturable absorber into a laser cavity involves complex processes and procedures. Mass production of graphene-based saturable absorbers requires simplification of the fabrication process with minimum material wastage. Reduced graphene oxide, a functionalized graphene, is found to have saturable absorption property as well. Comparatively, it is easier and more cost-effective to produce. On the other hand, optical deposition is a saturable absorber deposition technique that maximizes material utilization. In this work, commercially available reduced graphene oxide in N-methyl-2-pyrrolidone was used to fabricate a saturable absorber device via optical deposition, due to its simplicity and high efficacy. Optical pulse generation via Q-switching were successfully demonstrated with the optically deposited rGO-SA incorporated into a ring erbium-doped fiber laser. Pulse repetition rate of up to ~85.0 kHz and pulse durations as short as ~2.0 μs were achieved. Its performance as a saturable absorber in a Q-switched fiber laser is then compared with previous works. Comparatively, optically deposited rGO has a much lower Q-switched threshold and holds huge potential for mass production with maximum material utilization.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82105947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
