A method of positioning components on a support structure comprising the step of causing position changes by modifying at least a portion of the material of the support structure by inducing at least one of:
- a density change and
- an internal stress change.
A method of alignment and assembly of optical components, at least one of the optical components having an associated support structure, the method comprising the steps of:
- a) monitoring the optical coupling efficiency for the optical components;
- b) causing position changes of the at least one optical component in response to the coupling efficiency by modifying at least a portion of the material of the support structure by inducing at least one of density change, internal stress, and microstructure change to move the at least one optical component so as to achieve a substantially optimum optical coupling efficiency.
An optoelectronic package comprising:
- at least two optical components;
- and
- at least one support structure;
- one of the optical components being supported by the support structure wherein the optical alignment of the optical components has been effected through changes in a dimension of the support structure by modifying at least a portion of the material of the support structure by inducing at least one of:
- a density change,
- an internal stress change, and
- a microstructure change.
A method of positioning components on a support structure comprising the step of causing position changes by modifying the density of at least a portion of the material of the support structure.
An optical package for use in producing an optically aligned optical package comprising:
- at least two optical components;
- and
- at least one support structure;
- one of the optical components being supported by the support structure, the support structure comprising a material capable of undergoing crystalline phase changes that cause position changes for the optical component supported by the support structure.
An optical apparatus comprising:

A method of positioning optical components on a support structure comprising the step of causing position changes by inducing a dimension change in at least a portion of the material of the support structure.
A method of alignment and assembly of optical components, at least one of the optical components having an associated support structure, the method comprising the steps of:
- a) monitoring the optical coupling efficiency for the optical components;

An optoelectronic device comprising:
- at least two optical components;
- and
- at least one support structure;
