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.
Claims13
An optical structure comprising:
- a light source;
- a plurality of optical emitters on a common substrate, each configured to emit a light beam from a different respective portion of the common substrate;
- an optical power distribution network on the common substrate optically connecting the light source to the plurality of optical emitters, said optical power distribution network including a plurality of switches;
- and
- an array of optical receivers on the common substrate with the plurality of optical emitters and the optical power distribution network;
- 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 subset of the plurality of optical emitters;
- wherein a portion of the emitted optical power is subsequently reflected by an object;
- and
- wherein the reflected optical power is conveyed to the array of optical receivers configured to perform coherent detection based on the received reflected optical power.
