    摘要： An apparatus includes a plurality of demultiplexing modules, a plurality of multiplexing modules, and a plurality of N×N switching modules. Each demultiplexing module is connected to P N×N switching modules through optical fibers. Each multiplexing module is connected to P N×N switching modules through optical fibers. Demultiplexing modules and multiplexing modules are connected to same N×N switching modules. At least one N×N switching module connected to a target demultiplexing module has a function of switching optical signals of a plurality of wavelengths for the target demultiplexing module. A quantity of wavelengths of optical signals received by each N×N switching module connected to the target demultiplexing module from the target demultiplexing module is less than a target value, and the target value is a quantity of wavelengths of optical signals received by the target demultiplexing module.

    摘要： An optical switching apparatus is provided. The apparatus includes one or more input ports, a dispersion assembly, a first lens assembly, a redirection assembly, and one or more output ports. The input ports are configured to input a first beam into a dispersion assembly at a first angle of incidence in a first direction, and to input a second beam into the dispersion assembly at a second angle of incidence in the first direction. A difference between absolute values of the first angle of incidence and the second angle of incidence is not zero, and enables a first region in which spots of the first beam are arranged and a second region in which spots of the second beam are arranged to be separated from each other in the first direction, and enables the first region and the second region to at least partially overlap in a second direction.

    摘要： An illumination optical system configured to illuminate a mask on which a predetermined pattern is formed, includes a plurality of light sources configured to emit pulse lights, an optical system including a division part configured to divide the pulse lights emitted from the plurality of light sources into first pulse light and second pulse light, a delay optical system configured to guide the second pulse light to a second optical path longer than a first optical path through which the first pulse light passes, and a synthesis/division part configured to synthesize the first pulse light and the second pulse light passing through the delay optical system and divide and emit the synthesized pulse light, and an illumination system configured to guide the pulse lights emitted from the optical system to the mask and illuminate the mask.

    摘要： The imaging system has a photonic circuit chip that includes multiple cores that each includes a port through which an outgoing optical signal exits the photonic circuit chip. Each of the cores is configured such that the outgoing signal exits the photonic circuit chip traveling toward a location that is above or below the photonic circuit chip. Additionally, each of the cores is configured to combine light from one of the outgoing signals with a reference signal so as to generate a signal beating at a beat frequency. The imaging system also includes electronics that use the beat frequencies from the cores to calculate data that indicates a radial velocity and/or distance between the system and one or more objects located outside of the system.
