ABSTRACTAn ultracompact optical fiber Fabry–Perot interferometric sensor is proposed and demonstrated for inner diameter measurement of a capillary tube. The device is a section of single-mode fiber with an angle-polished end face of 45°. When the device is placed inside the capillary tube and in close contact with its inner wall surface, the reflected light from the angle-polished fiber end face is directed sequentially to the fiber core–cladding, cladding–air, and air–capillary interfaces, respectively, and reflected back, and finally returned to the fiber core after being reflected by the angle-polished fiber end face again. As a result, a cascaded Fabry–Perot interferometer system is constructed, which is well suitable for the inner diameter measurement of the capillary tube. Moreover, the wall thickness of the transparent capillary tube can also be conveniently measured by using the same device in slightly different configuration. The relative error of the measurement is small compared with the data provided by the manufacturer. Such a device is ultracompact, robust, flexible, and convenient in operation and is especially attractive for implementing the measurement in a tight or hard-to-reach spatial environment.KEYWORDS: Cascade F-P interferometerinner parameter measurementinterferometry Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work was supported by the the National Natural Science Foundation of China [61975192].Notes on contributorsQ.

ABSTRACTNowadays, there is an increasing need for advanced technological solutions due to concerns about the energy crisis and environmental protection. In particular, there has been a growing focus on developing green Information and Communication Technologies (ICT) solutions, as the energy consumption of ICT devices has been rapidly increasing in recent decades. This paper introduces EPSO-based flow-aware routing mechanisms that aim to minimize Queueing Delay, Power Consumption (Energy Dissipation), and Load Deviation. Two flow-aware mechanisms, namely, the Flow-aware load adaptive scheme (FA-LAR) and the flow-aware distance adaptive scheme (FA-DAR), are utilized in this study. The goal is to avoid traffic congestion across the routes by selecting the most direct and efficient paths for the flows. These routed paths are optimized using the MEPSO-based FA-DAR routing algorithm, resulting in significant energy savings. Extensive numerical simulations are conducted to evaluate the proposed algorithms using metrics such as throughput, routing efficiency, queuing delay, load deviation, and energy efficiency. The simulation results demonstrate that the proposed method outperforms existing benchmark methods in all metrics. Furthermore, it ensures lower power consumption, queuing delay, and load deviation. The method exhibits a 30% improvement in throughput and a 24% improvement in energy efficiency compared to existing benchmark methods.KEYWORDS: Flow-aware distance adaptive schemeFlow-aware load adaptive schemesroutingtraffic demandlink utilization Disclosure statementNo potential conflict of interest was reported by the author(s).Human and animal rightsThis article does not contain any studies with human or animal subjects performed by any of the authors.Informed consentInformed consent was obtained from all individual participants included in the study.Additional informationNotes on contributorsMathumohan SwamidossMathumohan Swamidoss obtained his Bachelor’s degree in Information Technology from St. Joseph’s College of Engineering, Chennai, Tamilnadu, India, and did his Master’s degree in Software Engineering from Rajalakshmi Engineering College, Chennai, Tamilnadu, India, and did his PhD Degree from Manonmaniam Sundaranar University, Tirunelveli, Tamilnadu, India.

ABSTRACT In this paper, high-order microring resonator filters coupled serially up to the 7th order are proposed for on-chip optical interconnects. This work mainly focuses on achieving a flat-top, higher out-of-band rejection ratio, and enhanced group delay value than previously demonstrated microring filters. Further, the effect of varying inter-resonator coupling coefficients on the filtering operation of wavelength 1552 nm is investigated, using the continued fraction method, and optimum conditions for coupling coefficients between ring-ring waveguides are realized to obtain steep edge response. The proposed design exhibits a minimum group delay of 7.457 ps at a coupling value of 0.04.

ABSTRACT This article presents an optical generation scheme of mm-wave carriers by 18-tupling of radio frequency (RF) signal using three cascaded Mach-Zehnder modulators. The proper selection of modulation index, biasing points and phase shifts leads to generation of desired ninth-order sidebands. A thorough mathematical analysis has been performed to validate the mm-wave generation and the results obtained are also consistent with simulation findings. Moreover, the effect of variation of key system parameters from their ideal values is also investigated. The higher tupling factor and elimination of optical filtering in the proposed scheme make it promising for implementation in radio-over-fiber (RoF) transmissions.

ABSTRACT In this work, compact praseodymium-doped fiber amplifiers (PDFAs) with single- and dual-pass configurations are designed and investigated in the O-band region based on theoretical simulation. 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.

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":"2 1","pages":"131 - 142"},"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}

ABSTRACT This paper proposes an all-optical switch using Kerr-type nonlinearity based on a photonic crystal ring resonator (PCRR). For the first time, the bar state and cross-state operation with 2 × 2 elements of an optical switch is implemented using a nonlinear ring resonator. Chalcogenide glass rods are used in the air background to simulate the proposed structure. The operating wavelength for this structure is calculated to be 1551 nm using the finite element method. The functional parameters such as the extinction ratio, response time, bit rate, crosstalk, and insertion loss values are studied using the finite-difference time-domain (FDTD) method. The presented structure design has a fast data rate of 0.46 Tbps, a low crosstalk value of −17.14 dB, and a fast response time of 2.16 ps. The proposed optical switch has a total footprint of about 398.56 μm2. The device’s performance makes it suitable for switching applications and integration in all-optical circuits.
