Abstract
Aspects of the present disclosure describe large scale steerable optical switched arrays that may be fabricated on a common substrate including many thousands or more emitters that may be arranged in a curved pattern at the focal plane of a lens thereby allowing the directional control of emitted light and selective reception of reflected light suitable for use in imaging, ranging, and sensing applications including accident avoidance.
Claims37
An optical structure comprising:
- a light source;
- a plurality of optical emitters;
- an optical power distribution network optically connecting the light source to the plurality of optical emitters, said optical power distribution network including a plurality of individually controllable switches;
- and
- a plurality of gratings, where two or more of the plurality of optical emitters is each configured to direct optical power to a corresponding one of the plurality of gratings;
- wherein said switches are configured such that optical power emitted from the light source that enters the optical power distribution network will be emitted from a selected subset of the plurality of optical emitters.

An optical structure comprising:
- a light source;
- a plurality of optical emitters;
- an optical power distribution network optically connecting the light source to the plurality of optical emitters, said optical power distribution network including a plurality of individually controllable switches, where the plurality of optical emitters are configured to emit from positions arranged over two dimensions of a plane;
- and
- an optical element positioned in the optical path of the emitted optical power and configured to produce a substantially flat focal plane coincident with the plane over which the positions of the plurality of optical emitters are arranged;
- wherein said switches are configured such that optical power emitted from the light source that enters the optical power distribution network will be emitted from a selected subset of the plurality of optical emitters.
