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 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 method of avoiding device failure caused by facet heating is described. The method is particularly applicable to a semiconductor laser. In the method, a semiconductor laser facet including GaAsN is hydrogenated such that the bandgap within the facet is greater than the bandgap in the active region of the InGaAsN laser. The increased bandgap reduces absorption of light in the facet and the associated heating that results.

摘要： A method and structure for adjusting the wavelength output of a semiconductor device is described. In the method, the hydrogen concentration in an active region of the semiconductor device is adjusted either during fabrication or after the device has been fabricated. The adjustment provides a simple technique for fine tuning many device types including regular lasers and VCSEL structures. The adjustment also allows for mass production of lasers of many different frequencies on a single wafer substrate, a system particularly desirable for wavelength division multiplexing systems.
