Patent ID: 7991254

Claim:
An optical package comprising a laser diode, coupling optics, a wavelength conversion device, and a multi-component mounting frame, wherein: the laser diode, coupling optics, and wavelength conversion device are configured to define an interfacial waveguide-to-waveguide optical path extending between opposing input/output facets of the laser diode and the wavelength conversion device; the coupling optics comprises a first lens component that creates a virtual magnified image V of the waveguide of one of the opposing facets with a magnification factor M 1 and a second lens component that creates a focused image of V at the remaining opposing facet with a magnification factor M 2 ; the virtual magnified image V is outside of the interfacial waveguide-to-waveguide optical path; the multi-component mounting frame comprises first and second frame components that independently fix the relative alignment of the first and second lens components; the first and second frame components are secured to each other such that angular misalignment between the first and second frame components originates along a fixation interface H that is outside of the interfacial waveguide-to-waveguide optical path; and the virtual magnified image V and the fixation interface H are both positioned on a common side of the coupling optics, either the laser diode side of the coupling optics or the wavelength conversion device side of the coupling optics.
