Polarization structured light 3D sensor Fig. 1: Principle of the polarization structured light 3D sensor. Full size image The polarization direction of the structured light emitted from TX is denoted by a double-head blue arrow in Fig.1a and its projection range is 75. 5° × 65. ...
a projection device adapted to project the modulated light beam; a first light shielding section, a part of the entrance surface being provided with the first light shielding section adapted to shield a part of the incident light beam to the effective entrance area; and a first opening section...
A six-channel all-silicon metasurface is specifically presented to project focused mid-infrared light to distinct positions at three wavelengths, each with a pair of arbitrarily chosen orthogonal polarizations. An isolation ratio of 117 between neighboring polarization channels is experimentally recorded, ...
We design and demonstrate a one-dimensional grating coupler with a low polarization-dependent loss(PDL) for large spatial light spots. Based on current fabrication conditions, we first utilize genetic algorithms to find the optimal grating structure including the distributions of duty and periods, maki...
In the past decade, a continous interest and a research effort have been dedicated to the study of spin injection into Semiconductor-based Light Emitting Device such as Spin-Light Emitting Diodes (Spin-LEDs) [1,2] and more recently Spin-LASERs such as Vertical Cavity Surface Emitting LASERs (...
the University of Stockholm generated state-independent fully contextual quantum correlations by performing compatible sequential measurements of the polarization and path of single photons, exploiting the fact that these sequences project any initial quantum state into one of the eigenstates of the KS ...

region were obtained using energy dispersive spectroscopy (EDS) (Xplore30, Oxford Instruments, USA). In addition, Raman spectra of CIPS films of different thicknesses were collected using a Renishaw Raman microscope (InVia Qontor, Renishaw, UK) with an incident excitation light source at 523 nm...
Wavelength multiplexers and demultiplexers combine and separate multi-wavelength lights, respectively, and are the key devices of WDM systems. However, owing to the change in the state of polarization (SOP) of light in the network fibers, the demultiplexers must be able to operate in arbitrary ...
