3.73 W all-solid-state dual-wavelength Nd:LuO crystal laser.

The laser output characteristics of : crystals were investigated in detail to obtain a dual-wavelength all-solid-state laser. Using 806 nm LD end-face pumped : crystals with lengths of 6 mm, a 1076 & 1080 nm laser outputs with a maximum output power of 3.73 W were obtained, with a slope efficiency of 30.

Design of ultrahigh-Q silicon microring resonators based on free-form curves.

A design method for ultrahigh-Q microring resonators (MRRs) based on Bezier free-form curves was proposed and demonstrated. An MRR consisting of a specially designed 180° waveguide bend, a directional coupler, and two low-loss multi-mode strip waveguides was designed. The free-form curves were used to increase the degree of freedom in the design, shaping the waveguide bend with a gradient width and curvature.

Color holographic display using single chip LCOS.

An algorithm for calculating a phase-only computer-generated hologram (CGH) for 3D color display using single chip liquid crystal on silicon (LCOS) is proposed. As an evolution of the G-S iteration, the proposed algorithm was obtained by replacing the Fresnel diffraction of single wavelength in the G-S algorithm with a color Fresnel diffraction process. Moreover, combined with "Ping-Pong" iteration, this algorithm was used to calculate 3D color holograms.
