Abstract:We propose two kinds of pair-structure plasmonic waveguides. Their gap mode properties are studied. It is found that very small mode areas can be obtained. Moreover, we calculate the optical forces that acting on the nanoparticle which is placed in the gap region of pair-structure waveguides. It is found that owing to the strong coupling between the pair structures, a strong local force(as much as more than 4000fN/W) can be generated, which is much stronger than those in most literatures. And the strength and range of the force can be adjusted by the parameters. With these features the pair-structure plasmonic waveguides may be applied as strong and tunable optical tweezers. | |||

Abstract:ZnO nanowires Metal-Semiconductor-Metal (MSM) photodetector with platinum (Pt) contact electrodes was fabricated and its optoelectronic properties were examined. The ZnO nanowires used in the experiment were synthesized by chemical vapor deposition method. The electrical performance and photoelectric response performance were studied, and the results showed that the Pt/ZnO nanowires based MSM ultraviolet photodetector exhibited a high sensitivity to 365 nm ultraviolet light, the photocurrent to dark current ratio can reach 9.44×103 with a voltage bias of 5 V, and the response and recovery time were also fast. Schottky barrier mechanism was employed to explain the results. | |||

Abstract:An analytical model for self-mixing interference based on erbium doped fiber laser is presented. The reflected or backscattered beam was introduced in the form of seed light. In this paper, we present a new procedure for solving numerically transcendental equation problem with standard root-finding technique, and obtained the emitted power of the laser in the self-mixing system. The self-mixing signal of velocity measurement under different parameters was also studied in detail. | |||
