Abstract
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 Ythat crosses a planar projection of the conversion layer of the wavelength conversion device. Subsequently, the crossing axis Yis offset and the intensity monitoring step is repeated as the beam spot is 1D scanned along an offset crossing axis Y.
