The ability to send high-speed messages between integrated circuit devices requires both high-frequency receivers and transmitters. The vast majority of integrated circuits are made from silicon-based semiconductors. Suitable receivers of silicon integrated circuits can be constructed from either metal-semiconductor-metal photodiodesl or P-type, intrinsic, N-type (PIN) photodiodes. These receiv...

High efficiency and a compact footprint are desired properties for electro-optic modulators. In this paper, we propose, theoretically investigate experimentally demonstrate recirculating phase modulator, which increases the modulation by modulating optical field several times in non-resonant waveguide structure. The 'recycling' of light is achieved looping path that exits modulator back couplin...

We propose and demonstrate an electro-optic spatial light modulator using a deep-proton-exchanged waveguide in periodically poled MgO:s-LiTaO3 thin crystal for UV laser light. The fine pixel profile, the good contrast and low driving voltage were accomplished at 355nm wavelength. Keywords-component; proton-exchage; domain inversion; lithium tantalate; spatial light modulator; ultraviolet (UV) l...

We demonstrate an aerial projection system for reconstructing 3D motion pictures based on holography. The system consists of an optical source, a spatial light modulator corresponding to a display and two parabolic mirrors. The spatial light modulator displays holograms calculated by computer and can reconstruct holographic motion pictures near the surface of the modulator. The two parabolic mi...

Detailed procedures for the modeling of synthesis load models (SLM) of actual power network are presented, then the classification indices based on 1oad characteristics and the principle of load classification are expounded. Based on the results of general investigation of 220 kV and 330 kV substations in China’s power grid, the load characteristics are classified, and detailed load characteris...

There are two widely held theories of color constancy based on very different mechanisms: Chromatic Adaptation and Spatial Comparisons. Chromatic Adaptation is based on the change of retinal sensitivity in response to changes in incident light. The Spatial Comparisons mechanism is insensitive to illumination changes because it uses ratios of radiance from different pixels in the image. A spatia...
