Abstract: An array of laser diode emitters is used as an illumination source for a range imaging system. The laser diode emitters are disposed on a common substrate. When one of the emitters fails, the remaining emitters emit enough light to meet the output optical power specification. The emitters can be disposed with a tight spacing. The tight spacing facilitates packaging of the entire array into a compact single package on a common heat sink.

Abstract: A light-emitting device may comprise a set of layers comprising a substrate layer, and a set of epitaxial layers deposited on the substrate layer. The set of epitaxial layers may include a strained layer. The strained layer may include a set of active zones to be used to generate optical gain. The light-emitting device may comprise a set of trenches etched into a subset of the set of layers of the light-emitting device. The set of trenches may prevent a set of defects or dislocations in a wafer from which the light-emitting device was formed from propagating into the set of active zones.
