Abstract: An optical system. A light source component generates a light beam. A light adjustment component adjusts a ratio of the S-polarized light and a ratio of the P-polarized light in the light beam. A first polarization beamsplitter mirror component splits a light beam adjusted by the light adjustment component into a first light beam and a second light beam, where the first light beam is a light beam of the S-polarized light, and the second light beam is a light beam of the P-polarized light. The first lens component projects the first light beam or a modulated first light beam to a first region. The second lens component projects the second light beam or a modulated second light beam to a second region.

Abstract: A liquid crystal on silicon, a wavelength selective switch, an alignment direction obtaining method, and a method for manufacturing a liquid crystal on silicon. The liquid crystal on silicon has a first pixel area, and a first liquid crystal located in the first pixel area. The first liquid crystal is deflected in a plane perpendicular to a first panel, and is deflected towards a first direction in a plane parallel to the first panel. An alignment direction of the first partial alignment film located in the first pixel area is deflected towards a second direction relative to a polarization direction of an incident beam, and the second direction is opposite to the first direction to reduce a loss of a deflected beam.

Abstract: The present invention provides a node apparatus, where two N×N wavelength selective switches are used to form a parallel-connected structure, and two ends of each power splitter are separately connected to input ends of the N×N wavelength selective switches, and two ends of each power combiner are separately connected to output ends of the N×N wavelength selective switches, thereby transferring route switching selection work originally performed between multiple 1×M wavelength selective switches to the inside of the N×N wavelength selective switch for implementation. Compared with an original structure using discrete components, the node apparatus is simplified, and when a traffic volume expands, the number of module slots on a line side does not need to be increased, thereby reducing usage costs eventually. The present invention is used for signal transmission in a node.
