Flexible gradually tapered metal waveguides (GTMWs) are fabricated by an inner plating silver film in a polycarbonate (PC) capillary for the transmission and imaging at 0.3 THz. It was demonstrated theoretically experimentally that GTMWs have lower losses smaller additional of bending, comparing with thin constant bore (CBMWs). Measured 1.95 dB 2.45 were obtained 1 m long GTMW size varying from 2.6 mm to 1.6 under straight one circle bending configuration. 4.48 dB/m 7.78 CBMW same bend...
Constrained data acquisitions, such as sparse view measurements, are sometimes used in photoacoustic computed tomography (PACT) to accelerate acquisition. However, it is challenging reconstruct high-quality images under scenarios. Iterative image reconstruction with regularization a typical choice solve this problem but suffers from artifacts. In paper, we present learned method suppress artifacts model-based iterative PACT. A lightweight dual-path network designed learn features both the...
A novel dual-cladding photonic crystal fiber (PCF) with elliptical As2S3 core has been proposed to obtain high-birefringence and high-nonlinearity in PCFs. a high refractive index nonlinear index, as result, it desired application on strengthening birefringence nonlinearity. Then outer cladding of the PCF contains hexagonal array circular air holes. holes is introduced near inner cladding. We find that could heighten nonlinearity obviously. The simulation results show 0.307 at wavelength...
We successfully demonstrate 32-Gbaud Probabilistically Shaped 4096-ary Quadrature Amplitude Modulation (PS-4096QAM) TeraHertz (THz) signal wired transmission at 325 GHz over the 1-m Hollow-Core Fiber (HCF) in a photon-assisted THz-wave communication system.

Terahertz imaging has been developed rapidly in recent years. However, conventional terahertz systems are often bulky due to the free space propagation. Various subwavelength sized probes have realize high resolution. However tiny suffer from loss. A flexible metallic polarization-maintaining (PM) hollow waveguides with elliptical cross section is investigated and fabricated. The waveguide used for transmitting linearly polarized (THz) radiation imaging. Bore size of on order wavelength....
