In the optical fiber communication system with physical signals to control or change the amplitude, frequency, phase, polarization and other characteristics of the optical carrier parameters of the process is called optical modulation. The role of optical modulation is to allow information to use the characteristics of the light wave itself to achieve high-speed processing and transmission, and can effectively inhibit the interference of external electromagnetic fields, so that the propagation of information is more stable. With the wide application of dense wavelength division multiplexing (DWDM) technology and the huge growth of fiber optic transmission capacity, SDH technology has long been overburdened, based on the wavelength selective switch (WSS) as the third generation of multi-functional reconfigurable optical insertion and multiplexing (ROADM) as a key device to realize the next generation of dynamic all-optical network, in recent years by the optical communication field research institutions attach great importance to, and has been rapid development.

Vortex phenomena are seen in life, such as bathtub vortices that occur when draining water, wake vortices that detach from ships as they travel, tornadoes, typhoons, and ocean circulation. Vortex light (carrying orbital angular momentum, OAM) was first discovered and applied mainly in the field of optics, i.e., the generation of vortex photons and vortex beams, and the concept of vortex beams was first proposed by Coullet et al. in 1989. In 1922, L. Allen et al. theoretically proved the existence of OAM in vortex beams, which pushed the field into the world's forefront.

Unsupervised deep learning for single-shot incoherent holographic 3D imaging

2024-06-24

Digital holography has attracted much attention for its ability to image 3D scenes from a single viewpoint. Compared with direct imaging, digital holography is an indirect multi-step imaging process that includes optical recording of holograms and numerical computational reconstruction, providing a wide range of application scenarios for computational imaging methods including deep learning. In recent years, incoherent digital holography has attracted much attention due to its high imaging resolution, absence of scattering noise and edge effects, and low cost. Currently, incoherent holography has been applied to aperture imaging, super-resolution imaging, large depth-of-field imaging and lattice light sheet microimaging.
