Abstract
An optical assembly includes a combination of laser sources emitting radiation, focused by a combination of lenses into optical waveguides. The optical waveguide and the laser source are permanently attached to a common carrier, while at least one of the lenses is attached to a holder that is an integral part of the carrier, but is free to move initially. Micromechanical techniques are used to adjust the position of the lens and holder, and then fix the holder it into place permanently using integrated heaters with solder.

-20. (canceled)
A method of making an aligned optical assembly, comprising:
- manipulating a lever holding a lens to position the lens to focus light from a first waveguide into a second waveguide, the first waveguide and the second waveguide, being physically coupled to a substrate and the lever having a fulcrum fixed in position with respect to substrate, the lever demagnifying movement of the lens in other than an optical axis of the light.
A method of making an aligned optical assembly, comprising:
- moving a lever holding a lens to position the lens to focus light from a first waveguide into a second waveguide, the first waveguide and the second waveguide being physically coupled to a substrate, with the lever having a point fixed with respect to the substrate and the lever having a length substantially parallel to an optical axis of the light from the first waveguide to the lens;
- and
- fixing position of the lever with the lens focusing light from the first waveguide into the second waveguide.
-34. (canceled)
A method of aligning an optical assembly, comprising:
- providing light from a first waveguide physically coupled to a substrate;
- providing an electric signal to an actuator to move a lens to focus light from the first waveguide into a second waveguide, the lens on a holder physically coupled to the first substrate, the actuator fixedly physically coupled to the holder;
- determining that the lens is focusing light from the first waveguide into the second waveguide;
- and
- fixing position of the holder.
