摘要： In the control of light condensing irradiation of laser light using a spatial light modulator, the number of wavelengths, a value of each wavelength, and incident conditions of the laser light are acquired, the number of light condensing points, and a light condensing position, a wavelength, and a light condensing intensity on each light condensing point are set, and a light condensing control pattern is set for each light condensing point. Then, a modulation pattern presented in the spatial light modulator is designed in consideration of the light condensing control pattern. Further, in the design of a modulation pattern, a design method focusing on an effect by a phase value of one pixel is used, and when evaluating a light condensing state, a propagation function to which a phase pattern opposite to the light condensing control pattern is added is used.

摘要： The present embodiment relates to a light emission device capable of removing zero-order light from output light of an S-iPM laser. The light emission device comprises an active layer and a phase modulation layer. The phase modulation layer includes a base layer and a plurality of modified refractive index regions. In a state in which a virtual square lattice is set on the phase modulation layer, a center of gravity of each modified refractive index region is separated from a corresponding lattice point, and a rotation angle around each lattice point that decides a position of the center of gravity of each modified refractive index region is set according to a phase distribution for forming an optical image. A lattice spacing and an emission wavelength satisfy a condition of M-point oscillation in a reciprocal lattice space of the phase modulation layer. A magnitude of at least one of in-plane wavenumber vectors in four directions formed in the reciprocal lattice space and each including a wavenumber spread corresponding to an angle spread of the output light is smaller than 2π/λ.

摘要： The embodiment relates to a light-emitting device in which a positional relationship between a modified refractive index region's gravity-center position and the associated lattice point differs from a conventional device, and a production method. In this device, a stacked body including a light-emitting portion and a phase modulation layer optically coupled to the light-emitting portion is on a substrate. The phase modulation layer includes a base layer and plural modified refractive index regions in the base layer. Each modified refractive index region's gravity-center position locates on a virtual straight line passing through a corresponding reference lattice point among lattice points of a virtual square lattice on the base layer's design plane. A distance between the reference lattice point and the modified refractive index region's gravity center along the virtual straight line is individually set such that this device outputs light forming an optical image.

摘要： A quantum simulator includes a pseudo speckle pattern generator, a main vacuum chamber, an atomic gas supply unit, a light beam generator, a photodetector, and an atom number detector. The pseudo speckle pattern generator generates a pseudo speckle pattern in the inside of the main vacuum chamber by light allowed to enter the inside of the main vacuum chamber through the second window. The pseudo speckle pattern generator includes a controller, a light source, a beam expander, a spatial light modulator, and a lens. The controller sets a modulation distribution of the spatial light modulator based on a two-dimensional pseudo random number pattern.
