20080204709 | BIOSENSOR USING MICRODISK LASER - 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. | 08-28-2008 |

20090053845 | Method For Controlling The Structure And Surface Qualities Of A Thin Film And Product Produced Thereby - A system and method for providing improved surface quality following removal of a substrate and template layers from a semiconductor structure provides an improved surface quality for a layer (such as a quantum well heterostructure active region) prior to bonding a heat sink/conductive substrate to the structure. Following the physical removal of a sapphire substrate, a sacrificial coating such as a spin-coat polymer photoresist is applied to an exposed GaN surface. This sacrificial coating provides a planar surface, generally parallel to the planes of the interfaces of the underlying layers. The sacrificial coating and etching conditions are selected such that the etch rate of the sacrificial coating approximately matches the etch rate of GaN and the underlying layers, so that the physical surface profile during etching approximates the physical surface profile of the sacrificial coating prior to etching. Following etching, a substrate is bonded to the exposed surface which acts as a heat sink and may be conductive providing for backside electrical contact to the active region. | 02-26-2009 |
