Abstract: In some implementations, a vertical cavity surface emitting laser (VCSEL) package may include a substrate. The VCSEL package may include a VCSEL disposed on a surface of the substrate. The VCSEL package may include a VCSEL driver disposed on the surface of the substrate. The VCSEL package may include an embedded capacitor electrically connected to the VCSEL and the VCSEL driver. The embedded capacitor may be formed from a subset of layers of the substrate. The capacitor may be associated with a first capacitance that is different from a second capacitance of at least one other capacitor associated with the substrate.

Abstract: In some implementations, an emitter module may include an emitter layer including a first emitter array configured to produce a first beam that provides flood illumination, and a second emitter array configured to produce a second beam that provides spot illumination. The emitter module may include a first optics layer, positioned in front of the emitter layer, that includes a first collimating lens positioned in front of the first emitter array, and a second collimating lens positioned in front of the second emitter array. The emitter module may include a second optics layer, positioned in front of the first optics layer, that includes an optical diffuser positioned in front of the first collimating lens, and a beamsplitter grating positioned in front of the second collimating lens.
