Random depolarization film, a polymer film doped with birefringent particles, can resolve blackout and color change problems of existing displays. This study optimized the dopant particle size with respect to image sharpness and color change of the display. Calcite microparticles improved the sharpness and color change, and realized real-color displays.

Convolution is an essential operation in signal processing and has found applications in convolutional neural networks. All-optical convolution is challenged by small nonlinear coefficients. Two configurations for all-optical convolution with nonlinear absorption are analysed and simulated to identify parameters for optimizing signal-to-noise.

To overcome the absorption limit of an ultra-thin layer, all-dielectric perfect absorbers of dipole modes can be realized based on degenerate critical coupling. Here, we propose theoretically a cross-shaped silicon perfect absorber of quadrupole modes in the visible region and demonstrate that the degenerate critical coupling applies to higher-order modes.

We demonstrated the fabrication of silicon valley photonic crystal structures with triangular air holes by using photolithography for the first time. The mask patterns we newly designed enable the formation of triangular air holes with reasonably high accuracy. This is an important step toward CMOS-compatible topological nanophotonics.

Well-rdered InGaN/GaN nanocolumn (NC) arrays with dislocation filtering and lattice strain relaxation properties can be used to enhance the visible luminous efficiency. These arrays were employed to realize the monolithic integration of multicolor NC micro LEDs, flip-chip bonding of NC LEDs on CuW, and random lasing in structurally graded NC photonic crystals.

We propose a hybridized plasmonic surface lattice resonance perovskite laser on the Ag nanoparticle array. The hybridization of plasmonic SLR and photonic waveguide mode dramatically improves the light-matter interaction. Via the experimental analysis, the high spontaneous emission factor can be obtained and shows the great potential in laser application.

We constructed an underwater optical wireless communication model with seawater absorption and simulated the propagation characteristic of Laguerre-Gaussian beams with multiple modes, and then exanimated for the application of those beams. As a result, the green OAM are expected to have better communication characteristics than Gaussian beams.

Surface plasmon sensors offer high sensitivity and real time measurement and are used in a wide range of fields such as environment, plant, biology, chemistry, medicine and physics. In order to realize high sensitivity and remote sensing of the fiber type device, we analyzed the structure dependence of the sensitivity at the communication wavelength of 1500 nm band for the device with a fiber tip and gold particles attached. Actualy we fabricated the sensors and achieved fundamental sensing operation with high sensitivity.
