The two main pump bands for 1319 and 1707 nm corresponding to the ^{6}H_{15/2}→^{6}H_{9/2} and ^{6}H_{15/2}→^{6}H_{13/2} transitions are discussed in detail. The predicted maximum slope efficiencies are determined to be ~7.8% and ~15.1% for the two pumping wavelength, respectively. Besides, the variety of laser performance has been systematically analyzed when the pump configurations, fiber length, fiber loss are varied. This numerical analysis might be useful to explore the 4.3 μm lasing operation for the mid-infrared chalcogenide fiber lasers in future.]]>1021111046<![CDATA[An Easy-to-Fabricate Radially Polarized Surface-Emitting Single-Mode Laser]]>10217786<![CDATA[A Unified Approach to Achieving High Power and High Energy in Chirally Coupled-Core Ytterbium-Doped Fiber Amplifier Systems]]>102183023<![CDATA[Spectral Purity Improvement by Combining Self-Injection Locking and Stimulated Thermal Rayleigh Scattering in Fiber Lasers]]>10219672<![CDATA[Widely Tunable Laser Using Reflecting Fabry–Perot Filters With Lossy Half-Wave Trenches]]>102191067<![CDATA[Stable Simultaneous CW 1052, 1071, and 1083 nm Narrow Spectral Width Nd-Based Laser Output Using Precise Gain Control With VBGs]]>10216716<![CDATA[High Reflectivity YDH/SiO2 Distributed Bragg Reflector for UV-C Wavelength Regime]]>2O_{3}-doped HfO_{2} (YDH)/SiO_{2} layers with high reflectivity spectrum centered at a wavelength of ~240 nm is fabricated using radio-frequency magnetron sputtering. Before the DBR deposition, optical properties for a single layer of YDH, SiO_{2}, and HfO_{2} thin films were studied using spectroscopic ellipsometry and spectrophotometry. To investigate the performance of YDH as a material for the high refractive index layer in the DBR, a comparison of its optical properties was made with HfO_{2} thin films. Due to larger optical bandgap, the YDH thin films demonstrated higher transparency, lower extinction coefficient, and lower absorption coefficient in the UV-C regime (especially for wavelengths below 250 nm) compared to the HfO_{2} thin films. The fabricated YDH/SiO_{2} DBR consisting of 15 periods achieved a reflectivity higher than 99.9% at the wavelength of ~240 nm with a stopband of ~50 nm. The high reflectivity and broad stopband of YDH/SiO_{2} DBRs will enable further advancement of various photonic devices such as vertical-cavity surface-emitting lasers, resonant-cavity light-emitting diodes, and resonant-cavity photodetectors operating in the UV-C wavelength regime.]]>10218713<![CDATA[Flexible Amorphous GeSn MSM Photodetectors]]>0.92Sn_{0.08} surface illuminated metal–semiconductor–metal (MSM) photodetectors on flexible substrates for visible wavelength. Photodetection at 633 nm is achieved with an I–V response up to 10^{–4} A for a 2 V bias voltage. Different evaporation rate effects on the amorphous GeSn MSM photodetector are examined. Bending/strain effects on device performance were studied by evaluating the current density versus voltage characteristics. Amorphous GeSn thin film deposition on polyethylene terephthalate flexible substrate and Ni/Au–GeSn–Ni/Au MSM photodetector finger pattern deposition were performed via thermal evaporation. Photocurrent and dark current densities of amorphous GeSn MSM photodetectors were obtained at 1.36 A/cm^{2} and 0.24 A/cm^{2}, respectively, where the photocurrent to dark current contrast ratio was found to be equal to 5.6. We also examined the evaporation rate, strain, and bending effect.]]>10219949<![CDATA[X-Ray Energy Self-Adaption High Dynamic Range (HDR) Imaging Based on Linear Constraints With Variable Energy]]>1021144046<![CDATA[The Depolarization Performances of the Polarized Light in Different Scattering Media Systems]]>102112851<![CDATA[Optical Implementation of Butler Matrix for Hardware-Efficient Multiuser Beamforming]]>10218890<![CDATA[Photonic Multiple Microwave Frequency Measurement Based on Frequency-to-Time Mapping]]>102171316<![CDATA[Terahertz Modulator Using 4-N,N-Dimethylamino-4′-N′-Methyl-Stilbazolium Tosylate (DAST)/Si Hybrid Structure]]>2.

Both the analytical and numerical solutions show that the stable elliptic optical solitons can be formed in nonlocal cubic, quantic, and competing CQ nonlinear media. The stability of soliton depends on the initial power, beamwidth, and characteristic length of the response function. In particular, there are bistable elliptic optical solitons in nonlocal media with self-focusing cubic and self-defocusing quintic nonlinearities when these nonlocal and nonlinear parameters are in the appropriate value domain.]]>102111947<![CDATA[Method for Polarization-Resolved Measurement of Electroabsorption]]>1021111776<![CDATA[Employing Microwave Graphene Field Effect Transistors for Infrared Radiation Detection]]>10217712<![CDATA[Mid-Infrared Sensor Based on a Suspended Microracetrack Resonator With Lateral Subwavelength-Grating Metamaterial Cladding]]>10218741<![CDATA[Dynamic Phase Measurement Based on Two-Step Spatial Carrier-Frequency Phase-Shifting Interferometry]]>1021111225<![CDATA[Cascaded Cross-Phase Modulation Instability in the Normal Dispersion Regime of a Birefringent Tellurite Microstructured Optical Fiber]]>10218831<![CDATA[Tunable Add–Drop Filter With Hollow Bottlelike Microresonators]]>102171096<![CDATA[Intensity Noise Suppression Using Dual-Polarization Dual-Parallel Modulator and Balanced Detector]]>10218857<![CDATA[Fiber-THz-Fiber Link for THz Signal Transmission]]>10216810<![CDATA[A Novel Concatenated Coded Modulation Based on GFDM for Access Optical Networks]]>10218924<![CDATA[OLS-Based RBF Neural Network for Nonlinear and Linear Impairments Compensation in the CO-OFDM System]]>Q threshold of 8.7 dB, and RBF-NN outperforms the linear equalizer by 2.8 and 5.6 dB Q-factors after 800 and 600 km transmissions, respectively.]]>10218884<![CDATA[3D Gerchberg-Saxton Optical Correlation]]>10219699<![CDATA[Research on Distortion Invariant Recognition of a Planar Integrated Optical Correlator]]>3 which is only half of the planar integrated 4F optical correlator.

Different from the traditional 3-D ONoC topology that needs seven-port ORs to realize the data transmission, the OR mentioned in our solutions only consumes six ports. This improvement effectively reduces the number of optical switching elements and cross waveguides in ORs, lowering the power consumption and hardware costs of the system. The simulation analysis based on the modified Noxim simulator demonstrates that our method performs well in terms of mitigating the OR- and network-level insertion loss, shrinking the floorplan/chip area and improving the network scalability over benchmarks.]]>1021101886<![CDATA[Secure OFDM Transmission Precoded by Chaotic Discrete Hartley Transform]]>178 to ensure the physical-layer confidentiality. An encrypted data transmission of 8.9 Gb/s 16-QAM optical OFDM signals is successfully demonstrated over 20 km standard single-mode fiber. Due to the effective reduction in PAPR by the chaotic DHT precoding matrix, the receiver sensitivity is improved by ∼1.4 dB ${(text{BER}@ 10}^{- 3})$. Moreover, the proposed scheme has low computational complexity, which also provides high spectral efficiency since no additional sideband information is required.]]>10219831<![CDATA[A 51.6 Mb/s Experimental VLC System Using a Monochromic Organic LED]]>102112920<![CDATA[OLED Panel Radiation Pattern and Its Impact on VLC Channel Characteristics]]>102110817<![CDATA[A Flexible Two-Way PM-Based Fiber-FSO Convergence System]]>102191046<![CDATA[Polarization Conjugated-Phase Component for Sorting Efficiently Vector Beams by Polarization Topological Charge]]>10216612<![CDATA[Highly Uniform White Light-Based Visible Light Communication Using Red, Green, and Blue Laser Diodes]]>10218709
