Dear editor, Video inpainting is a new technology of recovering the lost motion vectors or image blocks during the video sequence transmission. It aims to speculate the correct value of missing voxels from a given video to achieve the automatic inpainting and make the inpainted video frames present a natural visual effect. However, video inpainting remains challenging owing to the difficulties coming from computational complexity, complex scenarios and the high requirement on spatial and temporal consistency.
We demonstrate the first 1.2Tb/s/λ line rate IM/DD optical interconnects using ultra-high-order modulation and Stokes vector receiver. This achievement utilizes polarization division multiplexing and 154-GBd PS-PAM20...

Fabrication of optical fiber tapers is realized with a combination of plasmonic microheaters and specially designed structural bending of optical fibers,which provide the necessary elements of"heat and pull".The resultant compactness and flame-free condition enable monitoring of the tapering process inside a scanning electron microscope.
We propose an integrated spatial photonic Ising sampler using a high-uniformity multi-mode interferometer. It minimizes discrete and continuous spin Hamiltonians, achieves programmable spin couplings and external magn...
