Abstract
Methods of optimizing optical alignment in an optical package are provided. In one embodiment, the optical package includes a laser diode, a wavelength conversion device, coupling optics positioned along an optical path extending from the laser diode to the wavelength conversion device, and one or more adaptive actuators. The method involves adjusting the optical alignment of the wavelength conversion device in a non-adaptive degree of freedom by referring to a thermally-dependent output intensity profile of the laser diode and a thermally-dependent coupling efficiency profile of the optical package. The adjustment in the non-adaptive degree of freedom is quantified such that, over a given operating temperature range of the optical package, portions of the coupling efficiency profile characterized by relatively low coupling efficiency offset portions of the output intensity profile characterized by relatively high laser output intensity and portions of the coupling efficiency profile characterized by relatively high coupling efficiency offset portions of the output intensity profile characterized by relatively low laser output intensity. Additional embodiments are disclosed and claimed.
