One FPI (FPI-1) acts as the sensing unit while the other FPI (FPI-2) is used as the reference unit to generate the Vernier effect. The FPI-1 was prepared by fusion splicing a section of HCBF between a single-mode fiber (SMF) and a hollow silica tube (HST), and the FPI-2 was fabricated by sandwiching a piece of HCBF between two SMFs. Two FPIs with very different free spectral ranges (FSR) in the fringe pattern were connected to the 3-dB coupler parallelly, which realizes the harmonic Vernier effect and ensures the stability of the interference fringe. Both measurements of the air pressure in the range of 0-0.24 MPa and the temperature in the range of 25-55 °C were conducted using the dual FPIs sensor. Experimental results exhibited that high sensitivity of 124.35 nm/MPa with excellent linearity of 0.9967 was achieved by the sensing probe. Moreover, the calculated temperature crosstalk was as low as ~0.072 kPa/°C. The proposed sensor can be a promising candidate for real-time and high-precision gas pressure monitoring.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132763315","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}

Herein, we present a simple and elegant approach based on a single GaN LED that can self-adjust the output intensity in response to the changes in ambient intensity. The GaN LED with InGaN/GaN multi-quantum wells can operate in both luminescence and photodetection modes, and its electrical and optical performances are thoroughly investigated. Driven by a microcontroller board under pulse-width modulation, the device acts as a detector to provide photocurrent signals that reflect the ambient light intensity at the off state, and provides the desired intensity level at the on state. This work also exhibits a proof-of-concept demonstration of real-time stabilization of blue and white light irradiances at target areas despite large variations in ambient irradiance. The proposed novel self-adjusting scheme based on a dual-function LED chip without the need for external photosensors can be an alternative approach for smart lighting applications.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133315004","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}

On the one hand, conventional resistive strain gauges are susceptible to electromagnetic interference at high temperature. And on the other hand, common fiber sensors will be invalid under high-temperature environment, and may fall off under large strain conditions. In this paper, a precision measurement scheme that combining plasma surface treatment and metal oxide adhesive based on fiber Bragg grating (FBG) of large strain under high temperature environment is proposed, where three types of protection for the grating area of a FBG sensor were established, and a new plasma surface treatment method is theoretical analyzed and experimental studied. Suitable adhesive is also carefully selected according to the characteristics of the sample to be measured. After optimizing the mechanical transfer effect with the proposed method, effective coupling between the surface of the sample to be measured and the fiber grating sensor is realized, and large strain measurement up to 1200με under 1000°C environment is experimentally achieved.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132280091","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 influence of L-band attenuation on the optical signal-to-noise ratio (OSNR) of the system is analyzed and calculated; through the simulation of dense wavelength division multiplexing (DWDM) system, the requirements for fiber attenuation warping degree (FAWD) of CL fiber in 100Gbit/s rate DWDM system are obtained; and the CL fiber and its main attenuation parameters are defined. The results show that, the OSNR of L-band for conventional single-mode fiber will be 2dB-2.5dB worse than traditional C-band on 100km span system, so it is very important to limit the FAWD of L-band; if the L-band transmission can meet the link requirements in relevant standards, it is recommended that the FAWD Δα1625 of CL fiber is suitable to be controlled below 0.015dB/km, and the fiber attenuation warping degree difference (FAWDD) Δα is suitable to be controlled below 0.005dB/km.","PeriodicalId":177155,"journal":{"name":"2022 IEEE 7th Optoelectronics Global Conference (OGC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129222066","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}
