Abstract: A method for aligning an optical package including a semiconductor laser operable to emit an output beam having a first wavelength, a wavelength conversion device operable to convert the output beam to a second wavelength and adaptive optics configured to optically couple the output beam into a waveguide portion of an input facet of the wavelength conversion device includes measuring a power of light having a first wavelength emitted by or scattered from the wavelength conversion device as the output beam is scanned over the input facet of the wavelength conversion device along a first scanning axis. A power of light emitted from the wavelength conversion device is then measured as the output beam is scanned over the input facet along a second scanning axis. A position of the second scanning axis relative to an edge of the wavelength conversion device is based on the measured power of light having the first wavelength. The output beam is then aligned with the waveguide portion of the input facet based on the measured power of light having the second wavelength.

Abstract: Methods of controlling semiconductor lasers are provided where the semiconductor laser generates a wavelength-modulated output beam λMOD that is directed towards the input face of a wavelength conversion device. The intensity of a wavelength-converted output λCONV of the device is monitored as the output beam of the laser is modulated and as the position of the modulated output beam λMOD on the input face of the wavelength conversion device is varied. A maximum value of the monitored intensity is correlated with optimum coordinates representing the position of the modulated output beam λMOD on the input face of the wavelength conversion device. The optical package is operated in the data projection mode by directing an intensity-modulated laser beam from the semiconductor laser to the wavelength conversion device using the optimum positional coordinates. Additional embodiments are disclosed and claimed. Laser controllers and projections systems are also provided.

Abstract: A method for aligning a beam spot with a waveguide portion of a wavelength conversion device includes scanning a beam spot over the input face of the wavelength conversion device while measuring the output intensity of the device such that an output intensity for each of a plurality of fast scan lines is generated. A first alignment set point is then determined based on the output intensity of each fast scan line. A second scan of the beam spot is then performed over the fast scan line containing the first alignment set point while measuring the output intensity for each point along the fast scan line. A second alignment set point is then determined based on the output intensities measured during the second scan. The beam spot is then aligned with the waveguide portion using the first alignment set point and the second alignment set point.

Abstract: An optical reader system is described herein which has a single mode (SM) optical fiber launch/receive system that uses one or more SM optical fibers to interrogate a biosensor and does not use multimode (MM) optical fibers to interrogate the biosensor. The use of the SM optical fiber launch/receive system effectively reduces angular sensitivity, reduces unwanted system reflections, improves overall angular tolerance, and improves resonant peak reflectivity and resonant peak width. Two specific embodiments of the SM optical fiber launch/receive system are described herein which include: (1) a dual fiber collimator launch/receive system; and (2) a single fiber launch/receive system that interrogates the biosensor at a normal incidence.

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 applying a phase shifting signal I/VΦ to the phase section that is synched with a wavelength recovery portions in drive current IGAIN such that a plurality of cavity modes are shifted by one half of the free spectral range at each wavelength recovery portion. 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: An optical package includes a semiconductor laser, an adjustable mirror and a wavelength conversion device comprising a waveguide portion. The semiconductor laser, adjustable mirror, and wavelength conversion device are oriented to form an optical pathway between an output of the semiconductor laser and an input of the wavelength conversion device. The beam of the semiconductor laser is directed along the optical pathway and onto the adjustable mirror where the beam is reflected by the adjustable mirror onto the waveguide portion of the wavelength conversion device. The adjustable mirror may also be either thermally or mechanically deformable such that, when the adjustable mirror is deformed, the path of the beam along the optical pathway is altered thereby focusing the beam on the waveguide portion of the wavelength conversion device. The adjustable mirror may be adjusted such that the beam of the semiconductor laser is positioned on the waveguide portion of the wavelength conversion device.
