A device comprising: an illumination device for emitting an illumination beam, the illumination device comprising: an emitter array comprising multiple light emitters; and a meta-structure or micro-prism array comprising multiple transmission areas, the meta-structure of micro-prisms being positioned to receive light emitted from the emitter array, in which light from the meta-structure of micro-prism forms the illumination beam, in which a first one of said multiple transmission areas is arranged to emit light in a different direction than a second one of said multiple transmission areas.

Illumination device

A device includes an illumination device for emitting an illumination beam. The illumination device includes an emitter array including multiple light emitters; and a micro-lens array (MLA) including multiple micro-lenses. The MLA is positioned to receive light emitted from the emitter array. Light from the MLA forms the illumination beam. A first region of the MLA is offset from the emitter array by a first offset amount, and a second region of the MLA is offset from the emitter array by a second offset amount different than the first offset amount.

The emitter is configured to emit light at a second wavelength greater than the first wavelength.

Sidewalls laterally surround each optoelectronic device and can be in direct contact with sides of the optoelectronic device or, in some cases, with an overmold surrounding the optoelectronic device. The sidewalls can be composed, for example, of a vacuum injected material that is non-transparent to light emitted by or detectable by the optoelectronic device. The module also includes a passive optical element. Depending on the implementation, the passive optical element can be on a cover for the module, directly on a top surface of the optoelectronic device, or on an overmold surrounding the optoelectronic device.
