However, rare researches have focused on their saturable absorption properties and corresponding applications. Here we report a Q-switched polarization-maintaining fiber laser working at 1 μm based on double-rod gold metasurface as an SA. The periodic double-nanorod gold metasurface can provide a strong field enhancement by introducing Fano resonance and surface lattice resonance simultaneously, which is of benefit to significant nonlinear effects. Experimental results successfully confirm that the proposed gold metasurface can be implemented as a saturable absorber in a polarization-maintaining fiber laser for Q-switching operation. Typically, the passively Q-switched fiber laser could give output pulses at 1031.4 nm with a repetition rate of 34.1 kHz and a pulse width of 2.12 μs when pumped by a 976 nm laser diode of 155 mW. The repetition rate increases from 21.82 kHz to 35.76 kHz and the pulse width decreases from 3.38 μs to 1.92 μs when the pump power ranges from 105 mW to 160 mW.","PeriodicalId":422113,"journal":{"name":"Photonics and Optoelectronics Meetings","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126181771","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 magnetic fluid(MF) was injected into the air hole between two parallel fiber cores of the photonic crystal fiber, and then the two fiber cores of the twin-core photonic crystal fiber infiltrated with MF were tapered horizontally. A total reflection film was plated on the end face of the fusion cone of the twin-core photonic crystal fiber. The guided light was transmitted from the input port to the pull-cone area of the fiber, reflected by the reflection end face after mode coupling, and finally reflected from the output port to the output fiber. According to the above light transmission mode of reflective fiber coupler, The magnetic field measurement principle was studied, which the coupling region of twin-core photonic crystal fiber had been injected MF. The change of the effective refractive index will lead to the central wavelength shift of the fiber magnetic field coupler, and the magnetic field is measured by inquiring the wavelength shift of the transmission spectrum. The magnetic field response characteristics of the sensor were studied and analyzed through experiments. The experimental results show that the sensitivity of this method can reach 116pm/Oe. The fiber magnetic field sensor has the advantages of miniaturization, high sensitivity, and no electromagnetic interference. The magnetic field sensor can be widely used in the field of aviation, military, transportation, medicine and other fields of magnetic field accurate measurement.","PeriodicalId":422113,"journal":{"name":"Photonics and Optoelectronics Meetings","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131945567","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}

At present, the supercontinuum spectrum generated by photonic crystal fiber nonlinearity covers a wide range of wavelengths, while it is a challenge to make the spectral flat, especially in 1000-1200nm range. In comparison, ultra-broadband light sources generated by doped fibers have better flatness. Bi-doped glass and optical fibers have attracted much attention in the field of ultra-broadband light sources and optical amplifiers due to their ultra-broadband spontaneous emission. We prepared Bi-doped quartz glass by glass phase separation method, and synthesized Bi active center-Al (BAC-Al) in glass by controlling the valence state of Bi by sintering atmosphere, which possess luminescence at 1120nm. Yb and Bi were simultaneously incorporated into glass for achieving combined BAC-Al and Yb luminescence. The combined spectrum covers 1000-1250nm, and the half maximum full width can reach 150nm. Various properties of the glass are tested, and the luminescence of bismuth and ytterbium in the glass are studied. The energy transfer between Bi and Yb was discovered, which can help to infer the energy level of BAC-Al. This work not only provides new materials and methods for ultra-broadband light sources, but also provides new ideas for exploring the near-infrared luminescence principle of Bi.","PeriodicalId":422113,"journal":{"name":"Photonics and Optoelectronics Meetings","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131649376","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}

In addition to light emission, GaN-based quantum well diodes (QWDs) can convert light into electricity via the photovoltaic effect, simultaneously exhibiting inherent light emission and detection functionalities. Here, we report a LED with automatic brightness control utilizing the dual function of simultaneous light emission and detection, which is implemented on an III-nitride-on-silicon. Due to the inherent rapid photoelectric conversion of MQW diode, the diode is able to communicate with another. Using one MQW diode as the emitter, and another MQW diode as receiver, a visible light communication link was established. The overlap between the emission and detection spectra demonstrated that simultaneous emission-detection phenomenon also exists in MQW diodes. When the LED is modulated to emit light and we shine it with another modulated light beam at the same time, the LED operates under the simultaneous emissiondetection mode. The MQW diode converted external light into photocurrent as feedback to control circuit, by programming in one-chip computer, we can control the feedback circuit to turn the diode brighter or darker according to our willing. Utilizing the dual function of simultaneous light emission and detection of the MQW diode, the proposed MQW diode on its own can achieve real-time regulation of brightness without an external photodetector by integrating a programmed circuit.","PeriodicalId":422113,"journal":{"name":"Photonics and Optoelectronics Meetings","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125155116","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}
