We propose and experimentally demonstrate a real-time fiber-THz-fiber 2 × 2 multiple-input multiple-output (MIMO) seamless integration system at 340–510 GHz using commercial digital coherent opt…
Based on the novel concept of a fully-digitized module, we employ a forward-designed-assisted inverse design method to design a nonvolatile reconfigurable mode generator and an optical circulator, …
Geiger-mode InGaAsP/InP single photon avalanche photodiode (SPAD) with a low dark count rate (DCR) of 870 Hz at a photon detection efficiency (PDE) of 20% at 1064 nm is achieved for a 40 micron dia…
Angle of arrival (AOA) is one key parameter for passive signal source localization. However, with the increase in RF systems' instantaneous bandwidth and working frequency, it is a great challenge …
Structures matter in single image super-resolution (SISR). Benefiting from generative adversarial networks (GANs), recent studies have promoted the development of SISR by recovering photo-realistic…
Fondasi tiang merupakan jenis fondasi yang banyak digunakan di berbagai belahan dunia, terutama pada kondisi beban bangunan yang sangat besar. Dalam penggunaan fondasi kelompok tiang sangat penting…
In this paper, a fiber-tip all-optical photoacoustic (PA) transducer is demonstrated. The transducer is integrated by a silicon cantilever, a single optical fiber and a silicon dioxide tube. The ex…
Ex-situ rapid thermal treatments of 1–2.5 μm extended wavelength In 0.83 Ga 0.17 As/In 0.83 Al 0.17 As photodetector epiwafers on InP substrate were investigated. Enhanced photoluminescence inte…
Optical nonlinearity impairments have been a major obstacle for high-speed, long-haul and large-capacity optical transmission. In this paper, we propose a novel convolutional neural network (CNN)-b…
A photothermally generated microbubble on a single-mode fiber tip with tunable frequency bandwidth was demonstrated for sensitive detection of acoustic waves. The microbubble with spherical gas-wat…
