Abstract
The present disclosure relates to optical systems and methods for their manufacture. An example method includes coupling a first surface of a light-emitter substrate to a reference surface of a carrier substrate. The method also includes registering a mold structure with respect to the reference surface of the carrier substrate. Furthermore, the method includes using the mold structure to form an optical material over at least a portion of the light-emitter substrate. The optical material is shaped according to a shape of the mold structure and includes at least one registration feature. The method also includes coupling an optical lens element to the optical material such that the optical lens element is registered to the at least one registration feature.
Claims20
A method of manufacturing, the method comprising:
- coupling a first surface of a light-emitter substrate to a reference surface of a carrier substrate;
- registering a mold structure with respect to the reference surface of the carrier substrate;
- forming an optical material over at least a portion of the light-emitter substrate using the mold structure registered with respect to the reference surface, wherein the optical material is shaped according to a shape of the mold structure, and wherein the optical material comprises at least one registration feature;
- and
- coupling an optical lens element to the optical material such that the optical lens element is registered to the at least one registration feature.
A system comprising:
- a light-emitter substrate having a first surface;
- a carrier substrate having a reference surface and a backside surface, wherein the first surface of the light-emitter substrate is coupled to the reference surface of the carrier substrate;
- an optical material covering at least a portion of the light-emitter substrate and in contact with the reference surface, wherein the optical material comprises at least one registration feature;
- an optical lens element coupled to the at least one registration feature;
- and
- a further substrate coupled to the backside surface of the carrier substrate, wherein the further substrate comprises a control circuit.
