Patent ID: 8294130

Claim:
A method for optimizing the alignment of an optical package comprising a laser, a wavelength conversion device and at least one adjustable optical component oriented to create a folded optical pathway between the laser and the wavelength conversion device, the method comprising: directing a beam spot of the laser along the folded optical path and onto an input face of the wavelength conversion device with the adjustable optical component such that the beam spot is incident on a waveguide portion of the wavelength conversion device; measuring an output intensity of the wavelength conversion device; adjusting a position of the adjustable optical component about a first scanning axis thereby traversing the beam spot across the waveguide portion of the wavelength conversion device along a first scan line on the waveguide portion of the wavelength conversion device; determining a change in an output intensity of the wavelength conversion device based on an adjusted position of the adjustable optical component about the first scanning axis; adjusting the position of the adjustable optical component about a second scanning axis thereby traversing the beam spot across the waveguide portion of the wavelength conversion device along a second scan line; determining a change in the output intensity of the wavelength conversion device based on the adjusted position of the adjustable optical component about the second scanning axis; and repositioning the adjustable optical component on the first scanning axis and the second scanning axis based on the determined changes in the output intensity of the wavelength conversion device such that the alignment of the beam spot with the waveguide portion of the wavelength conversion device is optimized and the output intensity of the wavelength conversion device is maximized.
