Abstract
A micro-optical component includes a micro-substrate, a micro-optical element disposed on the micro-substrate, and a stand-off (a mechanical spacer) disposed on the micro-substrate or micro-optical component in a separate plane from the micro-substrate that at least partially encloses the micro-optical element. The micro-optical components can be stacked on a system substrate using micro-transfer printing to form a three-dimensional micro-optical structure. One more light beams can travel or pass through various combinations of multiple micro-optical components and micro-optical elements.

A micro-optical component, comprising:
- a micro-substrate;
- a micro-optical element disposed directly on the micro-substrate and extending from the micro-substrate in a direction;
- and
- a stand-off disposed on the micro-substrate or on the micro-optical element in a separate plane from the micro-substrate,
- wherein the micro-optical element is a passive optical component operable to modify light transmitted through an optical light path, and
- wherein the stand-off extends from the micro-substrate or the micro-element in the direction.
