    摘要: A fluidic structure includes a channel and along the channel is a series of sensing components to obtain information about objects traveling within the channel, such as droplets or other objects carried by fluid. At least one sensing component includes a set of cells of a photosensor array. The set of cells photosense a range of photon energies that emanate from objects, and include a subset of cells that photosense within subranges. A processor can receive information about objects from the sensing components and use it to obtain spectral information. The processor can perform an initial analysis using information from one set of sensing components and, based on the results, control a fluidic device in the channel, such as a gate, to retain objects, such as for concentration and more detailed analysis by other sensing components, or to purge objects from the channel.

    摘要: A compact sensor for detecting the presence of biological or chemical species includes a microdisk laser and a wavelength shift detector. The microdisk laser is coated with a biological or chemical recognition element, which binds preferentially with a target analyte. Because the recognition element and the target analyte adhere to the sidewall surface of the microdisk laser, they increase the effective diameter of the laser, which shifts the output wavelength by a detectable amount. The presence of a wavelength shift indicates the presence of the target analyte, and the magnitude of the wavelength shift corresponds to the mass load of the target analyte on the sidewall surface of the microdisk laser.

    摘要: A method and structure for integrating many optical devices on a single wafer is described. The method fabricates passive interconnect devices using hydrogenation techniques. Lateral optical confinement is achieved by hydrogenating regions laterally adjacent to the waveguide core. Vertical optical confinement is adjusted by careful control of the hydrogen content of the waveguide core itself.

    摘要: Disclosed is a compact, non-contacting device for collecting samples, and particularly minute quantities of bio-agents or particulates, from a surface. The device vibrates a region of a target surface containing the sample and collects the sample on an electrically charged pin array. The sample can be later released to a detector or other instrumentation for subsequent analysis.
