Abstract: An optical computing device includes: an optical modulation element including cells with independently configurable amounts of modulation; and a reflector. The optical modulation element is configured with N (N is a natural number not less than 2)-computing regions A1, A2, . . . , AN. The computing region A1 performs optical computing by modulating and reflecting incident light. Each computing region Ai (i is a corresponding natural number not less than 2 and not more than N) other than the computing region A1 performs the optical computing by modulating and reflecting signal light that has been modulated and reflected by a computing region Ai−1 and then reflected by the reflector.

Abstract: An optical computing device includes a filter, through which light passes, and an optical diffraction element group that performs optical computing. The optical diffraction element group includes one or more optical diffraction elements having microcells, each of the microcells having an independently set thickness or a refractive index. After passing through the filter, the light first enters a first optical diffraction element among the one or more optical diffraction elements. The filter selectively transmits light in a direction that has an angle, with respect to an optical axis of the first optical diffraction element, that is less than or equal to a specific angle determined by the filter.

Abstract: An optical switch that switches an optical path of signal light obtained by modulating carrier light by a control signal and a data signal, includes an optical modulation element that reflects or refracts the signal light and includes cells each having an independently set phase modulation amount with which the signal light is emitted in a direction corresponding to a ratio of a period of the control signal to a period of the carrier light.

Abstract: A structure having a microstructure or a nanostructure includes multi-block copolymers each having three or more segments including one or more first segments and one or more second segments. Each of the one or more first segments and the one or more second segments is constituted by one or more block polymers. Each of the one or more first segments has one of hydrophobicity and hydrophilicity, and each of the one or more second segments has the other of hydrophobicity and hydrophilicity. The one or more first segments and the one or more second segments are bonded in an alternating manner.
