    摘要： Techniques and structure are disclosed for implementing a spatial walk-off compensation mechanism having an integral tilt function. In some embodiments, the mechanism may comprise a tilt-ball mount having an integrated walk-off compensation medium. In some embodiments, the mechanism may be configured to receive an output beam from a non-linear converter (e.g., optical parametric oscillator or OPO) implementing a non-linear medium comprising a bi-refringent material (e.g., zinc germanium phosphide, or ZnGeP2; cadmium silicon phosphide, or CdSiP2). In some embodiments, the walk-off compensation medium may comprise the same material and/or have the same cut as the non-linear medium. In some embodiments, the mechanism may he manually and/or mechanically adjusted/repositioned to reduce beam walk-off and/or to more precisely direct the beam. In some embodiments, the mechanism may be implemented in mid-infrared (MIR) applications. Numerous configurations and variations will be apparent in light of this disclosure.

    摘要： Methods of positioning an optical unit in an optical package are provided. According to one method, a partially assembled optical package is provided. The wavelength conversion device within the package comprises a conversion layer having a waveguide portion formed therein. The optical unit is coarse-positioned in the optical package to direct light from the laser diode to the wavelength conversion device in the form of a beam spot on an input face of the wavelength conversion device. The intensity of the frequency-converted optical signal output from the wavelength conversion device is monitored as the position of the optical unit is modified to 1D scan the beam spot along a portion of a crossing axis Y1 that crosses a planar projection of the conversion layer of the wavelength conversion device. Subsequently, the crossing axis Y1 is offset and the intensity monitoring step is repeated as the beam spot is 1D scanned along an offset crossing axis Y2.

    摘要： Methods of positioning an optical unit in an optical package are provided. According to one method, a partially assembled optical package is provided. The wavelength conversion device within the package comprises a conversion layer having a waveguide portion formed therein. The optical unit is coarse-positioned in the optical package to direct light from the laser diode to the wavelength conversion device in the form of a beam spot on an input face of the wavelength conversion device. The intensity of the frequency-converted optical signal output from the wavelength conversion device is monitored as the position of the optical unit is modified to 1D scan the beam spot along a portion of a crossing axis Y1 that crosses a planar projection of the conversion layer of the wavelength conversion device. Subsequently, the crossing axis Y1 is offset and the intensity monitoring step is repeated as the beam spot is 1D scanned along an offset crossing axis Y2. This process is repeated until the monitored intensity during the 1D scan meets or exceeds a crossing threshold, at which time an optimum crossing axis Y* and a corresponding optimum crossing coordinate y along the optimum crossing axis Y* are identified by referring to respective intensity profiles of the monitored intensities. A full set of optimum coordinates x, y, z are subsequently identified by monitoring the intensity of a frequency-converted optical signal output from the wavelength conversion device as the position of the optical unit is modified to 1D scan the beam spot along a portion of one or more intersecting axes, one of which intersects the optimum crossing axis Y*. Additional embodiments are disclosed and claimed.
