Abstract: An optical reader system is described herein that uses a scanned optical beam to interrogate a biosensor to determine if a biomolecular binding event occurred on a surface of the biosensor. In one embodiment, the optical reader system includes a light source, a detector and a processor (e.g., computer, DSP). The light source outputs an optical beam which is scanned across a moving biosensor and while this is happening the detector collects the optical beam which is reflected from the biosensor. The computer processes the collected optical beam and records the resulting raw spectral or angle data which is a function of a position (and possibly time) on the biosensor. The processor can then analyze the raw data to create a spatial map of resonant wavelength (peak position) or resonant angle which indicates whether or not a biomolecular binding event occurred on the biosensor. Several other uses of the raw data are also described herein.

Abstract: Particular embodiments of the present invention relate generally to semiconductor lasers and laser scanning systems and, more particularly, to schemes for controlling semiconductor lasers. According to one embodiment of the present invention, a laser is configured for optical emission of encoded data. At least one parameter of the optical emission is a function of a drive current IGAIN injected into the gain section of the semiconductor laser and one or more additional drive currents I/VPHASE, I/VDBR. Mode selection in the semiconductor laser is altered by perturbing at least one of the additional drive currents I/VPHASE, I/VDBR with a perturbation signal I/VPTRB to alter mode selection in the semiconductor laser such that a plurality of different emission modes are selected in the semiconductor laser over a target emission period. In this manner, patterned variations in the wavelength or intensity profile of the laser can be disrupted to disguise patterned flaws that would otherwise be readily noticeable in the output of the laser.

Abstract: The present invention provides a variety of fluid lens configurations that enable beam steering and focus adjustment. For example, according to one aspect of the present invention, a fluid lens is configured such that an optical signal may propagate from an input side of the lens to an output side of the lens along an axis of optical propagation extending through first and second lens surfaces defined by the immiscible fluids of the lens. Respective tunable lens surfaces are formed along the interfaces between the immiscible fluids and an external signal is capable of changing the shape of those surfaces. Because the two lens components forming the lens surfaces are laterally offset, the focal length and beam steering of the lens can be tuned by varying the shape of the surfaces. Additional embodiments are disclosed.
