Abstract: A temperature-adjustable biochip assembly has a biochip with a microfluidic channel embedded inside and a temperature-controlling unit including a substance sited at a surface of the biochip, a cyclic guiding module passing through the substance, and a fluid flowed inside the cyclic guiding module, with the cyclic guiding module having a fluidic installed in the substance for guiding the fluid and a temperature-controlling component for modulating the temperature of fluid.

Abstract: A method of automatically coupling between a fiber and an optical waveguide is disclosed. Such a scheme is achieved by the property of the different etching rate in the various wafer direction on a semiconductor material, especial silicon, and the shrinking property of the glass soot formed by a flame hydrolysis deposition technique during a high temperature consolidation process, for improving aligning accuracy. The manufacturing process of the method is described below. First, a waveguide buffer layer is formed on a semiconductor substrate, then a waveguide layer is formed on the semiconductor substrate and the waveguide buffer layer. A part of the waveguide is manipulated to the planar optical waveguide, meanwhile, several windows which lead to the I/O end of the planar waveguide are formed on the other waveguide layer. The semiconductor substrate beneath the windows is etched anisotropically to form several aligning grooves.
